Novel heterobimetallic complexes [(PPh(3))(2)Cu(μ-SCOPh)(2)Cd(SCOPh)] (2a), [(PPh(3))(2)Cu(μ-SCOth)(2)Cd(SCOth)] (2b), [(PPh(3))(2)Ag(μ-SCOth)(2)Cd(SCOth)] (3a), [(PPh(3))(2)Ag(μ-SCOth)(2)Cd(H(2)O)(SCOth)] (3b), [(PPh(3))(2)Ag(μ-SCOPh)(2)Cd(SCOPh)] (3c), and a bimetallic complex PPh(3)Cd(μ-SCOth)SCOth·CH(2)Cl(2) (5) (th = thiophene) were prepared and characterized by single crystal X-ray diffraction analysis. A coordination polymer Cd(SCOPh)(2) (4) has also been characterized structurally that exhibited metal-like electrical conductivity. The heterobimetallic complexes on pyrolyzing under controlled conditions yielded ternary sulfides of composition CuCd(7)S(8), CuCd(10)S(11), Ag(2)Cd(8)S(9), and Ag(2)Cd(5)S(6), which have been characterized by SEM-EDX and X-ray diffractometry. Photophysical properties and electrical conductivities of the sulfides have also been studied.
新型杂双核配合物 [(PPh(3))(2)Cu(μ-SCOPh)(2)Cd(SCOPh)] (2a)、[(PPh(3))(2)Cu(μ-SCOth)(2)Cd(SCOth)] (2b)、[(PPh(3))(2)Ag(μ-SCOth)(2)Cd(SCOth)] (3a)、[(PPh(3))(2)Ag(μ-SCOth)(2)Cd(H(2)O)(SCOth)] (3b)、[(PPh(3))(2)Ag(μ-SCOPh)(2)Cd(SCOPh)] (3c) 和一个双核配合物 PPh(3)Cd(μ-SCOth)SCOth·CH(2)Cl(2) (5) (th = 噻吩) 已通过单晶 X 射线衍射分析进行了制备和表征。一个配位聚合物 Cd(SCOPh)(2) (4) 也已通过结构表征，表现出金属般的导电性。在受控条件下热解杂双核配合物得到组成式为 CuCd(7)S(8)、CuCd(10)S(11)、Ag(2)Cd(8)S(9)和 Ag(2)Cd(5)S(6)的三元硫化物，其通过 SEM-EDX 和 X 射线衍射进行了表征。硫化物的光物理性质和电导率也进行了研究。
