New organotin(IV) chlorides derived from N-(2-hydroxyphenyl)aryloxy sulfamates. Synthesis, characterization and DSC investigation

Three monomeric pentacoordinate organotin complexes were prepared by the reaction of dimethyltin dichloride with three N-(2-hydroxy)phenyl substituted aryloxy sulfamates in alkaline medium. The newly synthesized compounds were characterized on the basis of their infrared, CPMAS NMR, powder XRD diffraction and elemental analysis. The XRD powder analyses revealed a tetragonal system for two complexes, whereas the third one was crystallized in the...
