Synthetic and stereochemical features of some interesting boron complexes have been described.These three and four coordinated complexes have been prepared by the interaction of 2-isopropoxy-1, 3,2-benzodioxaborole with semicarbazones and thiosemicarbazones having the donor sets NOH and NSH in unimolar ratio and with semicarbazones and thiosemicarbazones having the donor sets HONOH and OHNSH in 1:1 and 2:1 molar ratios.Depending on the stoichiometry of the reactions, different moles of isopropanol are liberated and a variety of new boron azomethine complexes are obtained.On the basis of IR, (1)H NMR, (11)B NMR and (13)C NMR data plausible geometries have been proposed for the resulting derivatives, X-ray powder diffraction studies of a representative compound have also been carried out and the results show that adopts 'orthorhombic' type of lattice with unit cell dimensions; a= 10.84 Angstroem, b= 24.12 Angstroem, and c= 28.74 Angstroem.
