A recipe for the synthesis of diorganotin(iv) phosphonates in a colloidal regime by a solution based approach†
Abstract
This study presents the synthesis of diorganotin(IV) phosphonates, R2Sn{O3P(CH2)3SiR1R22} [R = Et, n-Bu; R1 = R2 = Me, Et or Ph] and Sn{O3P(CH2)3SiR1R22}2 featuring rod, rosette and spherical morphologies. The presence of silaalkylphosphonate ligands in the structural framework facilitates the transformation of bulk samples into a nano/colloidal domain by a facile solution based approach. The colloidal particles show enhanced antimicrobial activity against B. Subtilis bacteria as compared to their bulk counterparts.
