Bis(dimethylformamide-2O)dipyridine-1N,3N-bis(-2'-salicylbenzohydrazidato)-1³O,N,O':2²N,O'';2²N,O'':3³O,N,O'-trinickel(II) dimethylformamide disolvate hemihydrate

Abstract: In the trinuclear nickel(II) complex of the title compound, [Ni₃(C₃₀H₂₀N₄O₆)₂(C₅H₅N)₂(C₂H₆NO)₂]·2C₃H₇NO·0.5H₂O, the central Ni²⁺ ion is located on an inversion centre. This Ni²⁺ ion has a distorted octahedral coordination geometry involving two N and two O atoms from the 2'-salicylbenzohydrazidate ligands in the equatorial plane and two N atoms from two dimethylformamide molecules in the axial positions. The inversion-related outer Ni²⁺ ions, separated by 9.3038 (7) Å, have square-planar coordination environments.
