Popis: The title compound, [Ni4(C6H5N3O)2(C6H6N3O)2(C5H5N)4](NO3)2, is a tetranuclear nickel complex containing a single-decker cation, located on an inversion center. The two unique NiII cations are N,N′,N′′,O-chelated by carboximidamidate(2−) and carboximidamidate(1−) anions, forming a distorted four-coordinate planar structure, while the other two NiII atoms are N,N′,O,O′-chelated by the same bridging ligands and two pyridine molecules, affording six-coordinated metals in an octahedral geometry. The cation is isostructural with the complex crystallized with perchlorate counter-ions in place of nitrate.
