Abstract：
The complex [NiL2 (H2O)2 ] (NO3)2 was synthesized from 2 - ( p - methylphenyl) - 5 - (2 - pyridyl) - 1,3,4 - thiadiazole (L). Its single crystal structure was determined by X-ray analyses. Crystal data: space group P - 1, a = 7. 445 2(2) Å, b = 10. 132 6(2) Å, c = 11. 097 0(3) Å, α = 80. 587(2)°,β = 76. 233(2)°,γ = 70. 710(2)°,V = 764. 15(3)Å 3 , Z = 2. The central Ni1 atom is coordinated by four nitrogen atoms from two ligands of L and two oxygen atoms from two water molecules, and the Ni1 atom has a distorted octahedral geometry.
