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.
