主 题：trinickel(II) complex 4 amino 3 5 dimethyl 1 2 4 triazole thiocyanate crystal structure
摘 要：Reaction of nickel (II) perchlorate with 4 amino 3,5 dimethyl 1,2,4 triazole (admt) and NH 4NCS gave a trinuclear complex Ni 3(admtrz) 6(NCS) 6·C 2H 5OH·2H 2O, C 32 H 58 N 30 Ni 3O 3S 6. The compound crystallizes in the orthorhombic space group Pbca (#61) with a=13.551(3), b=25.146(6), c=16.553(4) , V=5640(2) 3, Z=4, M r=1279.47, D c =1.507 g/cm 3 ; μ (Mo Kα )=12.70 cm -1 and F (000)=2656. The final refinement with 2543 observed reflections is converged with R =0.058 and R w =0.069. In the Ni 3(admt) 6(NCS) 6 molecule, the central nickel atom is coordinated in a distorted octahedral environment by four triazole bridges and two thiocyanate bridges. The terminal nickel atoms are in addition coordinated by two thiocyanate and one admtrz ligand, and thus also have a distorted octahedral geometry. Ni-N distances are 2.040(7)-2.222(7), Ni-Ni distances are 3.411(1).
