Abstract:
A novel cadmium complexes of {[Cd(H 2biim) 2(SO 4)] ·3H 2O} n (1) (H 2biim=2, 2'-biimidazole) was synthesized by hydrothermal reaction of 3CdSO 4·8H 2O and 2, 2'-biimidazole ligand. The complex was built up by [Cd(H 2biim) 2] 2+ units bridged sequentially by SO 4 2- anions to form 1D zigzag chains parallel to the c-axis. The H 2biim ligands were attached to the 1D chain as branches of the chain by coordinating to Cd 2+ at two sides of the chain. The chains were held together by π-π interaction and O-H⋯O interactions, thus yielding a 3D extended supramolecular network. The responses of symmetric stretching vibration of SO 4 2-, N-C single bond, NC double bond and anti-symmetric stretching vibration of N-C single bond were detected in 2D IR correlation spectra under thermal perturbation. The complex exhibited strong blue emission peak at 498 nm (λ ex=397 nm) that can be assigned to a ligand-to-metal charge-transfer (LMCT) band.
