A new polymorph of the copper(II) thiocyanate complex with 2-dimethylaminoethanol, [Cu2(Me2Ea)2(NCS)2]1(HMe2Ea = 2-dimethylaminoethanol, HL)1, was isolated in the at- tempted synthesis of a mixed-metal complex from zerovalent copper, cadmium oxide and ammonium thiocyanate in CH3CN solution of HL in air. [Cu2(Me2Ea)2(NCS)2(DMSO)2]2is a product of recrystallization of1from DMSO. X-ray analysis carried out on single crystals for both compounds revealed that1is a rare example of a 1D coordination polymer consisting of two chains in which the metallic centres are connected through single end-to-end NCS groups.
The chains are inter-linked through alkoxo-bridges of L groups between the neighboring copper atoms. Complex2is a centrosymmetric dimer composed of two CuL(NCS)DMSO units linked by alkoxo-bridges of L groups.
