The one-dimensional coordination polymer poly[tetra­kis­[(4-chloro­phen­yl)methanaminium] [cadmate-μ-cyclo­hexa­phospho­rato]]

Cyclo­hexa­phospho­ric acid (P6O18H6) reacts with cadmium carbonate and 4-chloro­benzyl­amine (CBA) to give the mononuclear title complex, (C7H9ClN)4[Cd(P6O18)]n, in which the CdII atom, lying on an inversion centre, has an octa­hedral coordination built of six O atoms of two centrosymmetric P6O18 rings. Each P6O18 ligand acts as a bridge, linking two CdII atoms and forming an anionic coordination polymer [Cd(P6O18)4−]n extending along [010]. Adjacent polymeric chains are connected through N—H⋯O and C—H⋯O hydrogen bonds, generating a three-dimensional supra­molecular network

Homopiperazine-1,4-diium bis­[hexa­aqua­cobalt(II)] tris­ulfate

In the title compound, (C5H14N2)[Co(H2O)6]2(SO4)3, the cationic framework is built up of mixed organic–inorganic fragments, namely [Co(H2O)6]2+ and [C5H14N2]2+. The [Co(H2O)6]2+ cations form unconnected octa­hedra. Sulfate anions inter­calated between cationic species connect them via N—H⋯O and O—H⋯O hydrogen bonds and electrostatic inter­actions

2-Amino­pyrimidinium hydrogen sulfate

In the crystal structure of the title compound, C4H6N3 +·HSO4 −, hydrogen sulfate anions self-assemble through O—H⋯O hydrogen bonds, forming chains along the b axis, while the cations form centrosymmetric pairs via N—H⋯N hydrogen bonds. The 2-amino­pyrimidinium pairs are linked to the sulfate anions via N—H⋯O hydrogen bonds, forming a two-dimensional network parallel to (10). In addition, weak inter­molecular C—H⋯O contacts generate a three-dimensional network

(4-Chloro­phen­yl)methanaminium chloride hemihydrate

In the title hydrated salt, C7H9ClN+·Cl−·0.5H2O, the water O atom lies on a crystallographic twofold axis. In the crystal, the monoprotonated 4-chloro­benzyl­ammonium cation forms N—H⋯Cl and N—H⋯O hydrogen bonds and the water mol­ecule forms O—H⋯Cl hydrogen bonds, generating layers lying parallel to the bc plane

4-Chloro­anilinium hydrogen oxalate hemihydrate

In the title hydrated mol­ecular salt, C6H7ClN+·C2HO4 −·0.5H2O, the water O atom lies on a crystallographic twofold axis. In the crystal, the anions are linked by O—H⋯O hydrogen bonds, forming chains propagating along the b axis. These chains are inter­connected through O—H⋯O hydrogen bonds from the water mol­ecules and N—H⋯O hydrogen bonds from the cations, building layers parallel to the ab plane

2-Amino­pyrimidinium dihydrogen phosphate monohydrate

In the title compound, C4H6N3 +·H2O4P−·H2O, the pyrimidin­ium ring is essentially planar, with an r.m.s. deviation of 0.0016 Å. In the structure, pairs of symmetry-related anions are connected into centrosymmetric clusters via strong O—H⋯O hydrogen bonds forming six-membered rings with an R 2 2(6) motif. These clusters are inter­connected via water mol­ecules through OW—H⋯O hydrogen bonds, building an infinite layer parallel to the ab plane. Moreover, infinite chains of 2-amino­pyrimidinium cations spread along the a-axis direction. These chains are connected to the inorganic layer through N—H⋯O, C—H⋯O and C—H⋯N hydrogen bonds, which, together with electrostatic and van der Waals inter­actions, contribute to the cohesion and stability of the network in the crystal structure

Nutritional Assessment and Antioxidant Activities of Different Varieties of Vigna radiata

Three cultivars of Vigna radiata, namely, NM-92, NM-98, and NM-06, were analyzed for their proximate composition. The samples were also tested by HPLC for amino acid content. The data showed that all the varieties had same moisture level. The maximum ash content (4.29%) was present in NM-92, and crude fat (2.26%) was highest in NM-98 while NM-06 contained maximum amount of crude protein. About eighteen types of amino acids were detected in each of the three varieties. Acidic amino acids, that is, aspartic and glutamic acids, were in considerable amount ranged from 13 to 23% followed by leucine, isoleucine, alanine, valine, lysine, phenyl alanine, serine, and arginine which fell in the range of 3-8% of total protein. The maximum amount (13.00 and 22.80%) of aspartic and glutamic acids was present in NM-98. Similarly arginine (6.83%) and serine (5.45%) were also in highest amount in this variety. Leucine (7.46%) was maximum in NM-92 variety. NM-06 contained almost all the amino acids in lesser quantity except for few like threonine, proline, glycine, and alanine. It was concluded from the present study that varieties were of different nutritional value and HPLC was a sensitive method for amino acids determination. Antioxidant activities of all three varieties were also assayed and showed significant results

2,6-Diethyl­anilinium perchlorate

The asymmetric unit of the title mol­ecular salt, C10H16N+·ClO4 −, contains two cations and two anions. The atoms of one of the ethyl side chains of one of the cations are disordered over two sets of sites in a 0.531 (13):0.469 (13) ratio. In the crystal, the components are linked by N—H⋯O and bifurcated N—H⋯(O,O) hydrogen bonds and weaker C—H⋯O inter­actions, such that the organic cations alternate with the perchlorate anions, forming ribbons in the a-axis direction

1-Phenyl­piperazine-1,4-diium bis­(hydrogen sulfate)

In the title compound, C10H16N2 2+·2HSO4 −, the S atoms adopt slightly distorted tetra­hedral geometry and the diprotonated piperazine ring adopts a chair conformation. In the crystal, the 1-phenyl­piperazine-1,4-diium cations are anchored between chains formed by the sulfate entities via inter­molecular bifurcated N—H⋯(O,O) and weak C—H⋯O hydrogen bonds. These hydrogen bonds contribute to the cohesion and stability of the network of the crystal structure
