ABSTRACT
The title compound, [Fe(C2N3)2(C8H7N5)2]·2H2O, has been synthesized solvothermally and characterized by single-crystal X-ray diffraction. The octa-hedral iron coordination polyhedron contains two di(pyrimidin-2-yl)amine ligands coordinated in a bidentate fashion, and two monodentate dicyanimido ligands, each coordinated via a terminal N atom, with the latter in a cis orientation. The ligand configuration about the iron atom is chiral, although the compound crystallizes as a racemic mixture: the Fe-N distances (> 2.07â Å) are characteristic of high-spin iron(II). In the crystal, an extensive series of N-Hâ¯N, O-Hâ¯N and O-Hâ¯O hydrogen bonds links the independent mol-ecular components into a three-dimensional framework. The H atoms of both water mol-ecules are disordered. The structure also features some π-π and anion-π inter-actions. The inter-molecular inter-actions were investigated by Hirshfeld surface analysis and two-dimensional fingerprint plots. Comparisons are made with some related compounds.
ABSTRACT
The title compound, [Cu(C9H5N4O)2(C10H9N3)2], was synthesized solvothermally. The complex exhibits a distorted octa-hedral coordination geometry. The CuII atom is located on an inversion centre. The distorted octahedral CuN6 coordination sphere is composed of bidentate 2,2'-dipyrid-ylamine in the equatorial sites while the axial sites are occupied by 1,1,3,3-tetra-cyano-2-eth-oxy-propenide ligands. In the crystal, N-Hâ¯N hydrogen bonding results in chains parallel to [010].
