Abstract

Four novel organotin(IV) complexes containing phosphoric triamide ligands were synthesized and characterized by multinuclear (1H, 31P, 13C) NMR, infrared, ultraviolet and fluorescence spectroscopy as well as elemental analysis. The 1H NMR spectra of complexes 1–4 proved that the Sn atoms adopt octahedral configurations. The nanoparticles of the complexes were also prepared by ultrasonication, and their SEM micrographs indicated identical spherical morphologies with particles sizes about 20–25 nm. The fluorescence spectra exhibited blue shifts for the maximum wavelength of emission upon complexation.

Highlights

In recent years, the increasing progress in the preparation of nanomaterials has led to characterization of a great number of nanostructures [1]
New organotin(IV) complexes 1–4 were synthesized from the reaction of SnClR3 with phosphoric triamide ligands (Scheme 1)
The complexes 1 and 4 both contain SnCl2Me2, and they differ in the phosphoric triamide ligands

Summary

Introduction

The increasing progress in the preparation of nanomaterials has led to characterization of a great number of nanostructures [1]. As far as we know, there are no reports about the preparation of nanosized organotin(IV) complexes bearing phosphoric triamide ligands. In this work, following on from our previous works to prepare organometallic compounds including phosphoric triamide ligands [17,18], novel organotin(IV) complexes with the formula SnCl2(CH3)2L12 (1), SnCl2(OH2)2L12 (2), SnCl(C6H5)3L12 (3) and SnCl2(CH3)2L22 (4), where L1 = C6H5C(O)NHP(O)[NC4H8N(C6H5)]2 (5) and L2 = P(O)[NC4H8N(C6H5)]3 (6), were synthesized and characterized.
