Abstract
A new viologen(4,4′-bipyridinium)-based complex [N-ethyl-4,4′-bipyridinium][CdBr4], in which N-ethyl-4,4′-bipyri-dinium (EQ2+) has been generated in situ, has been synthesised via hydrothermal reaction and structurally characterised by single-crystal X-ray diffraction. [N-ethyl-4,4′-bipyridinium][CdBr4] features an isolated structure, based on an N-ethyl-4,4′-bipyridinium moiety and a cadmium atom terminally bound by four bromine atoms. Photoluminescence investigation reveals a broad and intense emission in blue region, which may originated from π → π* charge-transfer interaction of the N-ethyl-4,4′-bipyridinium moiety.
