Pseudobinuclear, [Bi(S 2 CN i Pr 2 ) 3 ] 2 , and Pseudopolymeric, [Bi(S 2 CN i Pr 2 ) 2 ][Bi(S 2 CN i Pr 2 )Cl 3 ], Bismuth(III) Complexes: Synthesis, Supramolecular Self-Assembly (the Role of Secondary Bi⋅⋅⋅S, Bi⋅⋅⋅Cl, and S⋅⋅⋅Cl Interactions), and Thermal Behavior

Pseudobinuclear, [Bi(S 2 CN i Pr 2 ) 3 ] 2 ( I ), and 1D pseudopolymeric, [Bi(S 2 CN i Pr 2 ) 2 ][Bi(S 2 CN i Pr 2 )Cl 3 ] ( II ), bismuth(III) complexes have been synthesized and structurally characterized. Secondary Bi⋅⋅⋅S, Bi⋅⋅⋅Cl, and S⋅⋅⋅Cl bonds combine mononuclear structural units of the complexes, playing a key role in self-assembly of their supramolecular structures. The thermal behavior of the compounds has been studied by simultaneous thermal analysis under an argon atmosphere. It has been determined by energy dispersive X-ray microanalysis and scanning electron microscopy that the residual substances after thermolysis of I / II are microcrystalline Bi 2 S 3 /Bi 2 S 3 , BiCl 3 .
