[(1,2,5,6-η)-Cyclo-octa-1,5-diene]bis-(thio-cyanato-κS)platinum(II)

摘要

In the title complex, [Pt(SCN) 2 (C 8 H 12 )], the Pt II ion lies in a square-planar coordination geometry defined by the mid-points of the two π -coordinated double bonds of cyclo-octa-1,5-diene and two S-bound SCN ? anions. The complex is disposed about a mirror plane passing through the Pt atom and the SCN ? ligands, and bis-ecting the cyclo-octa-1,5-diene mol-ecule. The room-temperature crystal structure of the title complex was previously reported in the ortho-rhom-bic space group Pna 2 1 [Musitu & Garcia-Blanco (1984). Acta Cryst. A 40 , C101]. The low-temperature structure presented herein represents a different (higher symmetry) ortho-rhom-bic space group Pnma whereby the Pt II atom lies on a mirror plane, lacking in the earlier study.
