TI  - Synthesis and spectral characterisation of chloro organotin (IV) di [3(2'-hydroxyphenyl)-5-(4-substituted pheny) pyrazolinates]
AB  - Chloro organotin(IV) dipyrazolinates of the type $RSnCl(C_{15}H_{12}N_2OX)_2$[where $C_{15}H_{12}N_2OX$ = 3(2'-Hydroxyphenyl)-5(4-X-phenyl)pyrazoline {where X = H (a); $CH_3$(b); $OCH_3$ (c); Cl (d) and R = Me, $Pr^n$ and Ph}] were synthesised by the reaction of $RSnCl_3$ 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 ($^1H$, $^{13}C$ and $^{119}Sn$)] studies. The bidentate behaviour of the pyrazoline ligands was confirmed by IR, $^1H$ and $^{13}C$ NMR spectral data. An octahedral structure around the tin(IV) atom for $RSnCl(C_{15}H_{12}N_2OX)_2$ is suggested.
