Abstract
Eighteen new diorganotin(IV) arsonates have been prepared by reacting R2Sno(R = CH3, n-C4H9, n-C8H17 and C6H5CH2−) and with methyl arsonic acid, benzylarsonic acid, 2-hydroxyethylarsonic acid, acetophenylarsonic acid and α,β-ethylenebis (phenylarsonic acid). The salts of n-butyl and n-octyltin(IV) with alkylarsonic acids have been found to be soluble in warm ethanol, benzene, chloroform However, all dimethyl-and dibenzyltin (IV) salts of α,β-ethylenebis (phenylarsonic acid) with diorganotin (IV) oxides have been found to be insoluble. Molecular weight determination in camphor shows the dibutyl and dioctyltin(IV) acetophenyl arsonates to be monomer while dibutyl-, dioctyltin(IV) methyl and benzyl arsonates are dimers. On the basis of infrare spectral data an octahedral structure with two alkyl groups in cis or in highly bent trans positions around tin (IV) has been suggested for all compounds.Keywords
