Bis[μ-N′-(adamantan-1-ylcarbonyl)-2-oxidobenzohydrazidato(3−)]tetrapyridinetrinickel(II) dimethylformamide monosolvate monohydrate

Abstract

In the title trinuclear NiII compound, [Ni3(C18H19N2O3)2(C5H5N)4]·C3H7NO·H2O, three NiII cations are bridged by two N′-(adamantan-1-ylcarbonyl)-2-oxidobenzohydrazidate trianions. The central NiII cation has a distorted octahedral N4O2 coordination environment where a reverse torsion occurs between the two bridging ligands, whereas the two NiII cations on the sides each adopt an N2O2 square-planar coordination. Weak intramolecular C—H...O and C—H...N interactions help to stabilize the molecular structure. In the crystal, the lattice water molecule links with the NiII complex and dimethylformamide solvent molecule via O—H...O hydrogen bonding.
