The molecular structure of the title compound, [FePt(CN)4(C14H8N2)2(H2O)2]n, consists of one-dimensional polymeric [–Fe–NC–Pt(CN)2–CN–]∞chains. Two water molecules and two monodentate 1,4-bis(pyridin-4-yl)buta-1,3-diyne (bpb) ligand molecules complete the octahedral coordination sphere of the FeIIatoms. The Fe—N(py) bond length (py is pyridine) is 2.2700 (15) Å, Fe—N(cyanide) is 2.1185 (16) Å and the Fe—O distance is 2.1275 (14) Å. The water molecules are hydrogen bonded to either bpb ligands or cyanide groups of the planar [Pt(CN)4]2−anion of adjacent polymeric chains. These O—H...N hydrogen bonds, in conjunction with offset and tilted π–π stacking interactions between bpb ligands and cyanide groups, extend the one-dimensional chains into a three-dimensional assembly.

Cl Atom

The racemic title compound, [Cu2(C7H8NO2)2Cl2], is composed of dinuclear molecules in which methoxy(pyridin-2-yl)methanolate ligands bridge two symmetry-related CuIIions. Each CuIIion is coordinated in a square-planar geometry by one Cl atom, the N and O atoms of the bidentate ligand and the bridging O atom of the centrosymmetrically related bidentate ligand. The separation between the two CuIIatoms is 3.005 (1) Å. In the crystal, non-classical C—H...O hydrogen bonds, weak π–π stacking [centroid–centroid distance = 4.073 (1) Å] and weak electrostatic Cu...Cl interactions [3.023 (1) Å] link the dinuclear molecules into chains running parallel to thebaxis.

The title compound, C2H10N2 2+·2Cl−·2C12H8N2·4H2O, has an inversion centre located midway between the two C atoms of the ethylenediammonium cation. The 1,10-phenanthroline molecules stack along the a axis, and are linked by π–π stacking interactions to form one-dimensional chains. These are bridged by ethylenediammonium cations, via hydrogen bonds, forming two-dimensional supramolecular sheets parallel to the ac plane. Hydrogen bonds to chloride anions and water molecules connect these two-dimensional sheets, resulting in the formation of a three-dimensional supramolecular network.

The structural chemistry of the title compound, [Pd(C32H22N3)2], at 173 K is described. The compound is comprised of two deprotonated (3,5-diphenyl-1H-pyrrol-2-yl)(3,5-diphenylpyrrol-2-ylidene)amine ligands coordinated to a central PdIIcation, which lies on an inversion centre and has distorted square-planar geometry.

The chelate plane makes a dihedral angle of 45.3 (2)° with respect to the central PdN4plane, giving a stepped conformation to the molecule. The complex displays simple intramolecular C—H...N hydrogen bonds, while the unit cell consists of discrete monomeric Pd(C32H22N3)2units which display intermolecular C—H...π interactions and limited intra- and intermolecular π–π stacking.
