Synthesis, Structure, Photoluminescence and Theoretical Study of {(N,Nʹ-Dimethyl-4,4ʹ-bipyridinium)[Cd2(μ2-Cl)4Cl2]}n with N,Nʹ-Dimethyl-4,4ʹ-bipyridinium Generated in Situ

The title complex, {(N,Nʹ-dimethyl-4,4ʹ-bipyridinium)[Cd2(μ2-Cl)4Cl2]}n (1), in which the N,Nʹ-dimethyl-4,4ʹ-bipyridinium was generated in situ, was synthesized via hydrothermal reaction. X-Ray diffraction analysis revealed that the structure of 1 consisted of MV2+ (MV2+ = N,Nʹ-dimethyl-4,4ʹ-bipyridinium) cationic moieties and infinite [Cd2(μ2-Cl)4Cl2]n anionic chains. The cadmium atom was bound by one terminal chlorine atom and four μ2-bridging chlorine atoms, yielding a slightly distorted triangular bipyramid. Photoluminescent investigation revealed that the complex displayed an emission in greenish blue r
