Abstract
Abstract Bis(N,N′-dimethylthiourea)copper(I)nitrate, Cu- (SC(NHCH3)2)2NO3, has been synthesized from an aqueous solution of copper(II) nitrate and N,N′- dimethylthiourea. Crystal data are a = 10.349(3), b = 12.197(2), c = 5.777(3) A, α =92.92(3), β = 98.84(3), γ = 68.03(2)°, V = 668.2 A3, space group P 1 , Z = 2. The crystal structure was solved by Patterson and Fourier methods from diffractometer data and refined to R and Rw of 0.038 and 0.041 including 3213 observed reflections. The compound exhibits a new structure type which has not yet been recognized in copper(I) sulfur complexes. Considerably distorted CuS4 tetrahedra are linked to isolated, infinite chains of the type [Cu(SR)2]nn+ by sharing opposite edges. The cationic chains are separated from each other by the nitrate anions, which do not coordinate to the metal atom. Shortest metal-to- metal distances within the chains are 2.865(1) and 2.934(1) A. The chains are bridged via NH···O hydrogen bonds involving the nitrate ions. A structural comparison between this compound and the copper(I) thiourea complexes hitherto known is presented.
