Complexes of CuHg(NCS)4, CuHg(NCS)2 (NCSe)2 and CuHg(NCSe)4 with tetrahydrofuran, dioxane, pyridine, 2-aminopyridine, nicotinamide, bipyridine and phenanthroline have been prepared and comparative studies made. Bipyridine and phenanthroline form cationic—anionic [CuL3]2+ [Hg(SCN)4]2? (L = bipy, phen) complexes with CuHg(NCS)4 and dinuclear bridged complexes with CuHg(NCSe)4 and CuHg(NCS)2 (NCSe)2. For other ligands the nature of the complexes is binuclear or polynuclear. The comparative stability of the -XCN- bridge (X = S, Se) is CuHg(NCSe)4 > CuHg(NCS)2 (NCSe)2 > CuHg(NCS)4. |
