N2 - A copper(II)-dicyanamide (dca = dicyanamide anion, [N(CN)2] -) compound, [Cu(dca)2(en)]n (1) (en = ethylene diamine), has been synthesized and its structure has been determined by single X-ray diffraction analysis. It crystallizes in the monoclinic space group C2/c with unit cell dimensions: a = 12.031(2) Å, b = 8.614(1) Å, c = 19.528(3) Å, β = 99.499°, Z = 8, and V = 1996.0(4) Å3. 1 is the first coordination polymer containing both μ1,5-dca and pseudo-μ1,3-bridging dca. The adjacent copper atoms are connected by dca with μ1,5-bridging mode to form a chain structure. Furthermore, the chains are cross linked via the pseudo-μ1,3-bridging dca into a 2D layer structure. Magnetic characterization of 1 suggests that the complex exhibits a weak antiferromagnetic interaction between the copper(II) ions.
