To investigate the effect of pseudo-halogen groups on the structure and optical properties of diorganotin(IV) coordination compounds the reaction of dimethyltin diisothiocyanate and dimethyltin dichloride with 1,2,3,4-tetra-(4-pyridyl)-butane (TPB) were studied. The results of spectroscopic data and structural analyses of prepared compounds showed that the reaction of Me 2 SnCl 2 with TPB ligand leads to the formation of a 2D organotin(IV) coordination polymer, while the replacement of chloride ions with thiocyanate ions as pseudohalogen groups in the structure of Me 2 SnCl 2 results in the development of a salt with an anion complex and a dimeric stannoxane as a side product. The results showed that the use of pseudo-halogen groups instead of halogen groups in the structure of diorganotin(IV) dihalogen compounds could be as a suitable factor in the control of the structure of diorganotin(IV) coordination compounds. The investigation of optical properties of prepared compounds demonstrated that the use of pseudo-halogen groups in the structure of diorganotin(IV) coordination compounds have an influence on their photoluminescence behavior.
