Synthesis and Crystal Structure of Bis-(2,2' bipyridyl)-2-pyrimidinethiolate-Ni(Ⅱ) Complex

The reaction between [Mn(bpy)2(MeOH)2](SbF6)2 (bpy = 2,2-bipyridine) and (Et4N)[Ni(pymt)3] (pymt = pyrimidine-2-thiolate) gave the complex [Ni(bpy)2(pymt)](SbF6) which was determined by X-ray single-crystal diffraction. The structure is of monoclinic with space group C2/c, a = 25.190(2), b = 11.3178(7), c = 19.296(1) ? b = 101.364(1)? V = 5393.4(6) 3, Mr = 718.98, Dc = 1.771 g/cm3, F(000) = 2840, m = 1.845 mm-1 and Z = 8. The final refinement gave R = 0.0641 and wR = 0.1399 for 3598 observed reflections (I > 2s(I)). The nickel(Ⅱ) atom is coordinated by four N donors from two bpy in the cis-conformation and two other atoms of S and N from one pymt, forming a distorted coordination octahedron.
