Bis(μ-2-phenyl­quinoline-4-carboxyl­ato)-κ3 O,O′:O;κ3 O:O,O′-bis­[(2,2′-bipyridine-κ2 N,N′)(2-phenyl­quinoline-4-carboxyl­ato-κ2 O,O′)cadmium(II)]

The neutral binuclear title complex, [Cd2(C16H10NO2)4(C10H8N2)2], is centrosymmetric, with the inversion center generating the central (μ-O)2Cd2 bridge. The CdII ion is in a strongly distorted CdN2O5 penta­gonal-bipyramidal geometry, defined by two N atoms from one 2,2′-bipyridine ligand and five O atoms from three 2-phenyl­quinoline-4-carboxyl­ate ligands, one monodentate, two bidentate. Weak inter­molecular π–π inter­actions [centroid–centroid distance = 3.712 (3) Å] help to establish the packing of the structure

(μ-4,4′-Bipyridine-κ2 N:N′)bis­[bis­(N,N-dimethyl­dithio­carbamato-κ2 S,S′)zinc(II)]

The title dinuclear ZnII complex, [Zn2(C3H6NS2)4(C10H8N2)], is centrosymmetric; the mid-point of the C—C bond linking the two pyridine rings is located on an inversion center. The pyridine N atom coordinates to the ZnII cation, which is also chelated by two dimethyl­dithio­carbamate anions, giving a trigonal-bipyramidal ZnNS4 geometry. Weak inter­molecular C—H⋯S hydrogen bonding is present in the crystal structure

Bis(1,10-phenanthroline-κ2 N,N′)[2-(4-sulfonato­anilino)acetato-κO]copper(II) dihydrate

In the title compound, [Cu(C8H7NO5S)(C12H8N2)2]·2H2O, the CuII ion is coordinated by four N atoms from two 1,10-phenanthroline (phen) ligands and one O atom from a 2-(4-sulfonato­anilino)acetate (spia) ligand in a distorted square-pyramidal geometry. Inter­molecular N—H⋯O and O—H⋯O hydrogen bonds, as well as π–π inter­actions between phen ligands and between phen and spia ligands [centroid–centroid distances = 3.663 (3), 3.768 (3) and 3.565 (3) Å], result in a three-dimensional supra­molecular structure

Bis(μ-2-phenyl­quinoline-4-carboxyl­ato)bis­[aqua­(1,10-phenanthroline)(2-phenyl­quinoline-4-carboxyl­ato)manganese(II)] dihydrate

In the centrosymmetric dinuclear title complex, [Mn2(C16H10NO2)4(C12H8N2)2(H2O)2]·2H2O, the MnII cation is in a distorted octa­hedral coordination geometry defined by two N atoms from a 1,10-phenanthroline ligand, one water O atom and three O atoms from three 2-phenyl­quinoline-4-carboxyl­ate anions. A pair of 2-phenyl­quinoline-4-carboxyl­ate anions bridge two Mn cations, forming the dinuclear mol­ecule. An intra­moleculr O—H⋯O hydrogen bond occurs. Inter­molecular O—H⋯O and O—H⋯N hydrogen bonds are present in the crystal structure
