Abstract
Three organotin (IV) derivatives PhPO3HSnBu2Cl, SnBu2Ph2PO2Cl×3/2H2O, Sn(PhPO3)Cl2×2H2O obtained on allowing PhPO3H2 or propylammonium PhPO3H to react with SnBu2Cl2, SnCl2×2H2O and two adducts [(C6H5CH2)2NH2]3O2C(CH2)2PO3×3SnPh3Cl, [CyNH3(HO2POCH2-N(CH2CO2H)2]2×3SnCl4.2H2O×NH4Cl obtained on allowing (C6H5CH2)NH2)3O2C(CH2)2PO3 or [CyNH3(HO2POCH2-N(CH2 CO2H)2]2 and SnPh3Cl or SnCl2×2H2O to react in ethanolic media have been characterized by elemental analyses, infrared and Mossbauer techniques. The suggested structures, while considering the anionic counterpart, are discrete, dimeric, double and triple metallic components or of infinite chain types, the anion behaving as a monochelating, a bichelating or a bidentate ligand. In OH containing structures, when extra hydrogen bonds are considered, supramolecular architectures may be obtained.
Highlights
The organotin (IV) compounds are known for several applications in the industrial field and as drugs against cancer [1, 2], that explains the focus of several research teams in the attempt to obtain new molecules of this family [3,4,5]
A two metallic components structure may be suggested: –a first metallic component is SnBu2(Ph2PO2 )2 which contains bridging anions and a trans octahedral environment around the tin centre leading to an infinite chain (4.46mm s-1); - a second metallic component H2O SnBu2Cl2 contains a Sn centre in a bipyramidal trigonal environment (3.16mm s-1)
These two metallic components may connect via hydrogen bonds to give the structure (Figure 3)
Summary
The organotin (IV) compounds are known for several applications in the industrial field (antifouling paints, wood preservatives) and as drugs against cancer [1, 2], that explains the focus of several research teams in the attempt to obtain new molecules of this family [3,4,5]. In the dynamic of our research activity, we have yet published many papers dealing with organotin chemistry [6,7,8,9,10]. In this paper we have initiated the study of the interactions between PhPO3H2, propylammonium PhPO3H, [(C6H5CH2)2NH2]3O2C(CH2)2PO3 or [(CyNH3)(HO2POCH2-N(CH2CO2H)2]2 and SnBu2Cl2, SnCl2 2H2O or SnPh3Cl which has yielded five new compounds. Infrared and Mossbauer studies were carried out and structures were suggested on the basis of the spectroscopic data
