Abstract
Five new nitrato adducts and derivatives have been synthesized and studied by infrared spectroscopy. The suggested structures are discrete or of infinite chain type, the nitrate behaving as a bidentate or a monodentate ligand, the environment around the tin (IV) centres being octahedral or trigonal bipyramidal. When extra hydrogen bonds are considered supramolecular architectures may be obtained.
Highlights
Organo- and halotin (IV) compounds are known for their several applications [1]
The compound A was obtained as a white powder on mixing methanolic solutions of SnPh3Cl, AgNO3 and methyl-2-imidazole in 1/1/1 ratio while the compound B was obtained as a white powder on allowing SntBu2Cl2 to react in ethanol with AgNO3 in 1/1 ratio
The compounds C, D and E were obtained as white powders on allowing MEIHNO3 to react with SnBu2(OCH3)2 in methanol (C) or SnCl2.2H2O in acetonitrile (D and E) respectively in 1/1, 2/1 and 1/1 ratio
Summary
Organo- and halotin (IV) compounds are known for their several applications [1]. Nitrato containing structures have been reported by several groups [2,3,4,5,6]. Seeking for new biologically active compounds, many groups including our have yet published several papers [7,8,9,10,11,12,13]. SnPh3Cl to react with AgNO3 and methyl-2-imidazole; SntBu2Cl2 -(tBu = tertiobutyl)- to react with AgNO3; MEIHNO3 -(MEI = methyl-2-imidazole)- to react with SnBu2(OCH3) or SnCl2.2H2O. This has yielded five new compounds, infrared study of which have been carried out structures suggested on the basis of infrared data
