DIRECT SYNTHESIS AND CRYSTAL, STRUCTURE OF THE POLYMERIC THIOCYANATE COMPLEXES OF COPPER(I)

The compounds Cu(SCN). CH3CN (1) and [(CH3)(3)NH](+) [Cu-2(SCN)(3)](-) (2) have been synthesized using a direct method of interaction and ch aracterized by X-ray crystallography. The planar Cu2S2 units with the copper-copper distances 3.095 (1) and 2.972 Angstrom (2) form the basi s of both structures. Complex 1 consists of the infinite puckered laye rs with the interlayer distance 6.657 Angstrom. The three-dimensional polymeric anion [Cu-2(SCN)(3)]- in compound 2 comprises two crystallog raphically independent copper(I) atoms and two bridging thiocyanate gr oups with different coordinations.
