S. Mathur et al., SYNTHESIS AND CHARACTERIZATION OF NONAISOPROPOXODIZIRCONATOTIN(IV) COMPLEXES, Indian journal of chemistry. Sect. A: Inorganic, physical, theoretical & analytical, 34(6), 1995, pp. 454-458
A number of novel heteroleptic nonaisopropoxodizirconatotin(IV) comple
xes of the type [Sn{Zr-2(OPri)(9)}Cl-n(4-n)] (where n=1-3) have been s
ynthesised by the reactions of SnCl4 with KZr2(OPri)(9), in benzene in
requisite (1:1, 1:2, or 1:3) molar ratios. Replacement df chloride in
these derivatives by an appropriate alkoxide affords volatile, hetero
bimetallic derivatives of the type [Sn{Zr-2(OPri)(9)}(n)(OR)(4-n)] (R=
Pr-i, Bu(t), n=2 or 3). These novel heterometal alkoxides have been ch
aracterized by elemental analyses,molecular weight measurements, IR an
d multinuclear (H-1, C-13 and Sn-119) NMR spectral studies.
