Özet

The title crystal structure, [Ni-3(C19H24N2O2)(2)(CHO2)(2)( C3H7NO)(2)], consists of discrete centrosymmetric homotrinuclear nickel complex molecules. In each molecule, the central Ni-II ion is in a distorted octahedral coordination environment, formed by four O atoms from two chelating DML2- ligands [DMLH2 = N,N'-bis(salicylidene)-2,2'dimethyl- 1,3- propanediamine] in the equatorial plane and two O atoms of two symmetry- related formate ligands in the axial positions. The terminal Ni-II ions also have distorted octahedral coordination environments and these are formed by two O and N atoms from chelating DML2- ligands in the equatorial plane; the axial positions are occupied by O atoms from a dimethylformamide ligand and a formate ligand. The overall result is three edge-shared octahedra in which the closest Ni center dot center dot center dot Ni distance is 3.0857 (14) A. The crystal structure is stabilized by weak C-H center dot center dot center dot O hydrogen bonds ( agnostic interactions).
