Abstract
Three cadmium compounds, [Cd2L2Cl(C6H5O7)]n (1), [CdLCl2] (2), and [CdL2(NO3)](NO3) · 2H2O (3) (L = 4'-Ph-terpy), were synthesized by hydrothermal methods from 4'-Ph-terpy and cadmium salts. The structure of 1 consists of a helical structure with cadmiums coordinated by 4'-Ph-terpy ligands and chloride and bridged by citrate, constructing a chiral 1-D polymeric compound. The cadmium in 2 is five-coordinate, bound to one tridentate terpyridine ligand and two chlorides, exhibiting a neutral mononuclear unit with an irregular CdN3Cl2 polyhedron. Compound 3 shows a seven-coordinate cadmium bound to two tridentate terpy ligands and one oxygen from nitrate in a mer configuration. The reactions producing these compounds are temperature dependent. The compounds show photo-luminescence in the solid state.
