TIN AND GERMANIUM COMPLEXES WITH MALTOL
No full textThe reaction of tin and germanium tetrachlorides with 3-hydroxy-2-methyl-4H-pyran-4-one (HMa) in benzene yielded M(HMa)(4)Cl-4.C6H6 (M = Sn or Ge) adducts, whereas in methanol the MMa(2)Cl(2) complexes have been isolated. Moreover, tin complexes with the neutral donors 2,6-dimethyl-4H-pyran-4-one (DMP) and 2,6-dimethyl-4H-pyran-4-thione (DMTP), having formulae Sn(L)(2)Cl-2 and Sn(L)(2)Cl-4(L = DMP or DMTP) have been prepared. The compounds have been characterized by ir and proton nmr spectroscopy and by thermogravimetric (TG and DTA) analysis. The thermal behaviour of all complexes has been followed to 1200 degrees C. The stability of the M(HMa)(4)Cl-4 adducts in various solvents is discussed on the basis of proton nmr spectr
