Abstract: The nickel(II) complexes dichlorobis(1-tert-butylimidazole-2-thione)nickel(II) [Ni(tmt-Bu)2Cl2] (1), dinitratobis(1-tert-butylimidazole-2-thione)nickel(II) [Ni(tmt-Bu)2(NO3)2] (2), dichloro-bis(3-phenyl-5-methyl-pyrazole)(1-tert-butylimidazole-2-thione)nickel(II) [Ni(pzPh,MeH)2(tmt-Bu)Cl2] (3) and dinitratobis(3-phenyl-5-methyl-pyrazole)(1-tert-butylimidazole-2-thione)nickel(II) [Ni(pzPh,MeH)2(tmt-Bu)(NO3)2] (4) have been synthesized and studied. The single crystal X-ray diffraction analysis was carried out for 1 and 4 {Bruker Kappa Apex-II CCD diffractometer, MoKα radiation}. Crystal data for 1: monoclinic C2/c, a = 16.949(2) Ã…, b = 8.6647(10) Ã…, c = 15.461(3) Ã…, β = 117.662(4)°, V = 2011.1(5) Ã…3, Z = 4, Dcalc = 1.460 g/cm3. Crystal data for 4: triclinic P-1, a = 9.9775(7) Ã…, b = 11.2254(8) Ã…, c = 14.8068(10) Ã…, α = 75.401(4)°, β = 87.422(4)°, γ = 74.874(4)°, V = 1548.86(19) Ã…3, Z = 2, Dcalc = 1.405 g/cm3. Coordination core of complex 1 adopts distorted tetrahedral geometry whereas core 4 has distorted octahedral geometry. The bonded nitrates are of two types coordinating as monodentate and bidentate ligands. © 2009 Springer Science+Business Media, Inc.
