Synthesis and Crystal Structure of the pi Copper(I) Cyanide Complex with N,N'-Diallyl Thiocarbamide 2CuCN centre dot (C3H5NH)2CS

摘要

Crystals of the pi copper(I) cyanide complex with N,N'-diallyl thiocarbamide,2CuCN centre dot (C3H5NH)2CS (I),are synthesized from an aqueous-methanol solution of potassium nitroprusside,diallyl thiocarbamide on a copper electrode using the method of alternating-current electrochemical synthesis.The crystals are monoclinic:space group P2_1,a = 6.9440(5) A,b = 13.760(1)) A,c = 12.733(1) A,beta = 97.280(9)°,V = 1206.8(2) A3,Z = 4,R = 0.0361,R_w = 0.0362 for 2836 independent reflections with F >= 4 sigma(F).A unique polymeric structure is built due to the Cu(I)-(C=C) pi bond and the bridging function of the thioamide S atom of the ligand molecule and one of the two independent cyano groups.
