Sažetak (engleski)

The structure of both cadmium methoxide and cadmium ethoxide
is of a partially ordered random-layer type. X-ray diffraction patterns can be interpreted in terms of hexagonal crystal lattice with unit-cell parameters: a = 3.494(3), c = 8.36(1) A for cadmium methoxide, a = 3.482(3), c = 8.98(1) A for cadmium ethoxide. Powder diffractometer data for both compounds and IR spectrum for cadmium ethoxide are given.The stability of the compounds was checked at room temperature in air. Thermal decomposition was investigated by DTA and X-ray diffraction. The decomposition of cadmium ethoxide resu.lts
in the formation of CdO, while the element al Cd and, to a much smaller extent, CdO are products of the decomposition of cadmium
methoxide. The decomposition of cadmium methoxide and ethoxide
was also studied by mass spectrometry. The mechanism of decomposition is discussed. The intermediate formation of carbene, :CH2, is suggested in decomposition of cadmium methoxide.
