Bis[μ-4-amino-3,5-bis(hydroxymethyl)-1,2,4-triazole]bis{bis[4-amino-3,5-bis(hydroxymethyl)-1,2,4-triazole]nickel(II)} tetranitrate methanol disolvate

Abstract

The title complex, [Ni2(C4H8N4O2)6](NO3)4·2CH4O, contains a centrosymmetric binuclear nickel(II) complex bridged by a pair of 4-amino-3,5-bis(hydroxymethyl)-1,2,4-triazole ligands. The separation between the NiII atoms is 3.962 (1) Å. The Ni atoms are in a slightly distorted octahedral coordination. Intermolecular N—H...O, N—H...N and O—H...O hydrogen bonds connect the ligands, solvent molecules and nitrate ions.
