Bis[N-(Isonitrosoacetophenone)-N'- Benzoylhydrazonato- K~3O,N,N']Nickel(II) Dimethylformamide Disolvate Hemihydrate: Synthesis, Crystal Structure, and Spectroscopic and Electronic Properties

摘要

In the title complex, [Ni(C_(30)H_(24)N6O4)]2 · 4C3H7NO · H2O (I), the Ni(II) atoms are six-coordinated by two N atoms and one O atom of each of the two tridendate benzoylhydrazone ligands, leading to a distorted octahedral geometry. In the environment of Ni(II) atoms, the equatorial planes are approximately perpendicular. The structure is stabilized by O—H···O, O—H···N, and C—H···O intra- and intermolecular hydrogen bonding, resulting in the formation of infinite chains running along the x axis of the triclinic cell. The structure of the compound was characterized by IR and UV spectra, elemental analyses, and X-ray diffraction techniques.
