A new Cu(I)-dicyanamide with formula [Cu2(L)(dca)2]n(dca = dicyanamide anion,L = 1,4-bis(3-furanyl)-2,3-diaza-1,3-butadiene) has been synthesized and structurally characterized.The complex crystallizes in the monoclinic system,space group P21/n with a = 9.271(2),b = 7.7355(16),c = 11.967(3),β = 102.693(3)°,V = 837.3(3)3,Z = 4,Mr = 223.68,Dc = 1.775 g/cm3,μ(MoKα) = 2.567 mm-1,F(000) = 444,R = 0.0782 and wR = 0.2582 for 951 observed reflections(I > 2σ(I)).Single-crystal X-ray analysis reveals that the copper atom is three-coordinated by two nitrogen atoms from two dicyanamide anions and another one from the ligand,and each copper atom is connected by two [N(CN)2]-anions to form an infinite double-stranded bridge fashion leading to 1D ladder-like motifs.
