ABSTRACT
The title compound, [Ni(4)(C(6)H(5)N(3)O)(2)(C(6)H(6)N(3)O)(2)(C(5)H(5)N)(4)](NO(3))(2), is a tetra-nuclear nickel complex containing a single-decker cation, located on an inversion center. The two unique Ni(II) cations are N,N',N'',O-chelated by carbox-imid-amid-ate(2-) and carboximidamidate(1-) anions, forming a distorted four-coordinate planar structure, while the other two Ni(II) atoms are N,N',O,O'-chelated by the same bridging ligands and two pyridine mol-ecules, affording six-coordinated metals in an octa-hedral geometry. The cation is isostructural with the complex crystallized with perchlorate counter-ions in place of nitrate.
