trans-Diacetonitriletetrakis(1H-pyrazole-κN2)nickel(II) dinitrate
Abstract
In the title complex, [Ni(CH3CN)2(C3H4N2)4](NO3)2, the cation lies on an inversion center and adopts an octahedral coordination geometry about the Ni atom. The two acetonitrile ligands are in a trans conformation. N—H...O hydrogen bonds between cations and anions link the complex molecules into one-dimensional chains running parallel to [100].
