Synthesis, crystal structure and luminescent properties of two cadmium thiocyanate coordination polymers with benzylpyridyl cations

Two luminescent Cd(II) complexes [RBzPy][Cd(SCN)3] for R = Cl (1) and Br (2) have been synthesized and structurally characterized. The Cd atoms are all N3S3 hexa-coordinated with six bridging SCN− and form infinite [Cd(SCN)3]∞ polymeric chains. The layer arrangement of the anionic chains was obtained using the larger halogenated benzylpyridyl cations. The luminescent properties of 1 and 2 in the solid state were investigated.

The luminescent measurements showed broad blue-fluorescent emissions band with a maximum at 490 nm for 1 and 484 nm for 2.Figure optionsDownload full-size imageDownload as PowerPoint slide
