| Popis: | The crystal and molecular structure of trans-dichloro(1,4,8,11-tetraazacyclotetradecaneN,N',N'',N'')chromium(III) isothiocyanate has been determined. The cyclam (1,4,8,11-tetraazacyclotetradecane) moiety exists in a chair conformation located on a crystallographic centre of symmetry. The equatorial nitrogen ligands and the central chromium ion are exactly coplanar. The isothiocyanate counterion exhibits statistical disorder, the ion being straddled across the inversion centre with the C atom close to (0.5, 0, 0) |
