Organometal complexes

Several diorgano- and dihalotin(IV) derivatives of new β-diketonate donors, 1,3-dimethyl-4-R(CO)pyrazol-5-ones (R=Me, QDH; R=Ph, QMH) have been synthesized and characterized with analytical and spectroscopic methods. They are stable monomeric species, very soluble not only in aromatic and chlorohydrocarbon solvents, but also in alcohols and hydroalcoholic solutions. In the solid state, the diorganotin(IV) derivatives adopt a skewed trapezoidal...
