Solvothermal reaction of copper(Ⅰ)cyanide(CuCN)with triphenylphosphine(Ph3P)in anhydrous tetrahydrofuran(THF)leads to a CuCN-based coordination polymer Cua(CN)a(PPha)4(1)by using standard Schlenk techniques.This complex crystallizes in triclinic,space group P-1 with a = 13.281(7),b = 13.330(7),c = 20.654(11)(A),α = 103.028(5),β =96.824(5),γ = 101.916(5)°,V = 3433(3)(A)3,Dc = 1.275 g/cm3,Z = 2,C75H60Cu3N3P4,Mr =1317.76,μ= 1.057 mm-l,λ(MoKa)= 0.71073 A and F(000)= 1356.6975 observed reflections with Ⅰ＞ 20(Ⅰ)and 766 parameters gave R = 0.0669,wR = 0.1403 and S = 1.005.The structure exhibits a special stair-like chain along the[111]direction constructed from cyanide groups alternately connecting the Cu(Ⅰ)and Cu(PPh3)2 moieties.These stair-like chains are further stacked together via abundant π-π and C-H…π interactions to form a 3-D structure.
