Synthesis and Structure of Some Diorganotin(IV) with N-methyl-m- nitrobenzohydroxamic Acid

Tin(IV) and organotin(IV) compounds, a deceptively simple area of inorganic and metal-organic chemistry, have been receiving more attention due to the important industrial (Tammy and Georges, 2005) and environmental applications. Nitrogen, oxygen, and sulfur donor ligands have been used to enhance the biological activity of organotin derivatives (Mohammad et al., 2004; Jason et al., 2000). Also organotin compounds with such ligands have widely been tested for their possible use in cancer chemotherapy (Shang et al. 2008; Zhou et al. 2005). The coordination chemistry of tin is extensive with various geometries and coordination numbers known for both inorganic and organometallic complexes (Katsoulakou et al. 2008; Baul et al., 2007). Hydroxamic acids constitute a very important class of chelating agents with versatile biological activity (Farkas et al. 2002; Wang et al. 2003). In view of the diverse fields of applications of organotin complexes, we have synthesized new ligand N-
