Isomerism among Binuclear Thiocyanatobridged Complexes


WE earlier described1 two isomeric platinous complexes of the general formula (PPrn3)2Pt2(SCN)2Cl2, which we designated α (melting point, 144–152° C.) and β (melting point, 173–174.5° C.). These were shown to have trans-symmetrical structures of type (I), where A, B, C and D represent the thiocyanato- and chloro-groups.
