[rac-2-(1-Aminoethyl)phenyl-κ2 C 1,N](ethylendiamine-κ2 N,N′)palladium(II) 3-methylbenzoate monohydrate
In the title compound, [Pd(C8H10N)(C2H8N2)](C8H7O2)·H2O, the palladium ion is coordinated in a distorted square-planar fashion by the two N atoms from the chelating ethylenediamine group and by the N and a C atom of the deprotonated chiral amine. The resulting cationic complex, the 3-methylbenzoate anion and the hydrate water molecule are interconnected by N—H⋯O and O—H⋯O hydrogen bonds
Pyridine-2,6-dicarboxaldehyde bis[(diphenylmethylidene)hydrazone]
The title compound, C33H25N5, belongs to the family of pyridine-2,6-dicarboxaldehyde Schiff bases which possess a terdentate coordinating site (–N=C–C=N–C–C=N–) similar to terpyridine derivatives. The dihedral angles between pairs of terminal rings are 69.67 (9) and 66.23 (9)°. The shortest distance between the centroids of aromatic rings in neighbouring molecules is 3.8080 (14) Å
Tris[4-(2-pyridylmethyleneamino)phenol]iron(II) bis(perchlorate)
In the title compound, [Fe(C12H10N2O)3](ClO4)2, the metal center is coordinated by six N atoms from the three bidentate chelating ligands in a distorted octahedral coordination geometry, with overall formation of the meridional (OC-6-21) isomer. Intermolecular O—H⋯O hydrogen bonds between the hydroxyl groups of the cation and the counter-anions form an infinite one-dimensional chain in the c-axis direction
Triaquabis[4-(methoxycarbonyl)benzoato-κO 1]zinc dihydrate
In the crystal structure of the title complex, [Zn(C9H7O4)2(H2O)3]·2H2O, the Zn atom and the apical aqua ligand are located on a crystallographic twofold axis, with the ZnII ion in a distorted square-pyramidal coordination geometry composed of five O atoms, two from the monodentate methylterephthalato group and three from water molecules. The resulting complex and the two hydrate water molecules are interconnected by O—H⋯O hydrogen bonds
