A novel cadmium(II) based metal organic framework, [Cd(3-bpd)(SCN)₂]_n (1) where 3-bpd = 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene has been synthesized and characterized by elemental analysis, various spectroscopic techniques, TGA and single crystal X-ray diffraction analysis. X-ray analysis shows the formation of an undulated polymeric two-dimensional network parallel to the (0 −1 1) plane. Current conduction properties of 1 have been explored in the dark and in the presence of light. The study shows that current conduction of the complex increases with the increase of the incident light intensity. On progression of intensity of glancing radiation the photosensitivity of 1 has been increased. The time dependent light response on charge carrier conduction reveals that complex 1 may uncover new ground to explore in optoelectronic switching applications.
