1. Se-Ru-CuCl system
When [SeRu5(CO)14]2− was treat with different equiv. of CuCl under different conditions, a series of Se-Ru-CO complexes [SeRu5(CO)14CuCl]2−, [SeRu5(CO)14(CuCl)2]2− , [Se2Ru10(CO)28Cu4Cl2]2−, and [Se2Ru4(CO)10Cu2Cl2]2− were isolated.
Complexes [Se2Ru10(CO)28Cu4Cl2]2− and [Se2Ru4(CO)10Cu2Cl2]2− were observed in the course of the reaction of [SeRu5(CO)14CuCl]2− with one equivalent of CuCl, proving the transformation relationship between these complexes. DFT calculations were applied to understand experimental results.
2. E-Cr-Mn (E = S, Se ) system
In Te-Cr-Mn system, the triangle bipyramidal [PPN]2[Te2CrMn2(CO)9] can transfer into the pyramidal [PPN]2[Te2CrMn2(CO)10] upon the CO addition, but not in E-Cr-Mn (E = S, Se) system. DFT calculations were applied to understand experimental results. Complexe [PPN]2[Te2Cr2Mn2(CO)18], precursor of [PPN]2[Te2CrMn2(CO)9], now can be synthesized in a more simple way.
3. Se-Mn system
The reaction of [Se2Mn3(CO)9]− with one equivalent of Cr(CO)6 under 4 M KOH/MeOH solution produced [HSe2CrMn3(CO)14]2− and octahedral [Se2CrMn3(CO)12]3−.
Further reation of [HSe2CrMn3(CO)14]2− with Cr(CO)6 in the refluxing CH2Cl2 produced a symmetric complex [HSe2Cr2Mn3(CO)19]2−. [HSe2Cr2Mn3(CO)19]2− can reconvert back to [HSe2CrMn3(CO)14]2− upon the CO addition in THF. DFT calculations were applied to understand the experimental results.
