Three novel thiocyanate cadmium(II) compounds [Cd(ind)2(SCN)2]n (1), [Cd(dpa)Cl(SCN)]n (2) and [Cd(terpy)(SCN)2] (3) were synthesized and characterized by spectroscopic and crystallographic methods. Thiocyanate ions of 1 act as bridging ligands generating a one-dimensional chain constructed of Cd(SCN)2Cd units and expanding along the crystallographic direction [1 0 0]. The Cd(II) ions of 2 are bridged by alternating di-μ-Cl and di-μ1,3-NCS bridges to one-dimensional chain running along the crystallographic direction [0 1 0]. [Cd(terpy)(SCN)2] (3) is a square pyramidal mononuclear compound.The fluorescence properties of the complexes 1 and 2 were examined in solid state, whereas fluorescence spectra of 3 were recorded in both solid state and solution. All they were compared with the fluorescence properties of the free ligands. Additionally, the electronic spectrum of 3 were investigated at the TDDFT level employing B3LYP functional in combination with LANL2DZ.
Graphical abstractThree novel thiocyanate cadmium(II) complexes were synthesized and characterized by spectroscopic and crystallographic methods. Two of them, [Cd(ind)2(SCN)2]n (1) and [Cd(dpa)Cl(SCN)]n (2) create infinite one-dimensional coordination structure.
