Abstract

Graphical abstract: Copper(I) thiocyanate forms complexes {[Cu(SCN)(Me2 S)2 ]} n, {[Cu(SCN)(Me2 S)]} n, {[CuSCN)(Et2 S)]} n, {[(CuSCN)(Pr i 2 S)]} n, and {[(CuSCN)(THT)2 ]} n (THT = tetrahydrothiophene). In the Me2 S and THT complexes the zigzag chains are formed. In the Et2 S and Pr i 2 S complexes ladders are formed. Alkyl sulfide ligands are monodentate in all cases. Abstract: A total of five new CuSCN-L compounds with alkyl sulfide ligands, L = methyl sulfide (Me2 S), ethyl sulfide (Et2 S), isopropyl sulfide (Pr i 2 S) or tetrahydrothiophene (THT) have been prepared and characterized. X-ray crystal structures for four of the compounds were obtained. Two compounds were collected from solutions of CuSCN in Me2 S: {[Cu(SCN)(Me2 S)2 ]} n (1a ) in the form of colorless blocks and (CuSCN)(Me2 S) (1b ) as a white powder. Neat mixtures of CuSCN in the other alkyl sulfide ligands yielded only one product each: {[Cu(SCN)(Et2 S)]} n (2 ); {[Cu(SCN)(Pr i 2 S)]} n (3 ); and {[Cu(SCN)(THT)2 ]} n (4 ). Crystals of2 and4 underwent destructive phase changes at lower temperatures. Two networks types were observed: 1:2 decorated 1-D chains (1a and4 ) and 1:2 decorated 1-D ladders (2 and3 ). Further network formation through bridging of the organic sulfide ligands was not observed.
