A dinuclear nickel(II) compound: μ-{N, N, N′, N′-tetrakis[2-(3, 5-dimethyl-1-pyrazolyl)ethyl]-1, 2- ethylenediamine}-bis[aqua(nitrato-Ο, Ο + ′)nickel(II)] dinitrate dimethanol solvate
The title compound, [Ni2(NO3)2(C30H48N 10)(H2O)2]-(NO3) 2.2CH3OH, contains a doubly charged cation which lies across an inversion center. The hexadentate ligand N,N,N′,N′-tetrakis[2-(3,5-dimethyl-1-pyrazolyl)-ethyl]-1,2- ethylenediamine (tped) holds two NiII ions at a distance of 6.3721 (13) Å. A distorted octahedron around each NiII ion is denned by two pyrazole N atoms of tped at distances of 2.023 (4) and 2.048 (4) Å, one amine N atom of tped at a distance of 2.161 (4) Å, two O atoms of a chelating nitrate anion at distances of 2.144 (3) and 2.205 (4) Å, and a water O atom at a distance of 2.032 (4) Å. A one-dimensional hydrogen-bonding network running along the a axis connects the methanol molecule of crystallization to the nitrato and aqua ligands of different cations, and an aqua ligand to the non-coordinated nitrate ion. The structure is essentially isomorphous with the previously reported CuII analog [Driessen, Haanstra & Reedijk (1992). Acta Cryst. C48, 1585-1587], the main differences being that NO3 is involved in bidentate coordination to NiII and in a bifurcated hydrogen bond with methanol, whereas in the CuII complex, it is monodentate and only one of its O atoms hydrogen bonds to methanol.
