Abstract
Chloro organotin(IV) dipyrazolinates of the type RSnCl(C15H12N2OX)2 [where C15H12N2OX = 3(2'-Hydroxyphenyl)-5(4-X-phenyl)pyrazoline {where X = H (a); CH3 (b); OCH3 (c); Cl (d) and R = Me, Prn and Ph] were synthesised by the reaction of RSnCl3 with sodium salt of pyrazolines in 1:2 molar ratio, in anhydrous benzene. These newly synthesised derivatives were characterised by elemental analysis (C, H, N, Cl and Sn), molecular weight measurement and spectral [IR and multinuclear NMR (1H, 13C and 119Sn)] studies. The bidentate behaviour of the pyrazoline ligands was confirmed by IR, 1H and 13C NMR spectral data. An octahedral structure around the tin(IV) atom for RSnCl(C15H12N2OX)2 is suggested.
