Summary: | The row of coordination compounds of germanium (IV) with 1-hydroxyethylene- diphosphonic acid H4Oedph is synthesized: complex acid (I) and its complexes with exo-ligands (L): hydrazide of isonicotinic acid Ind (II), diphenylguanidine Dphg (III), pyracitam Pam (IV), imidazole Im (V) and citozine Ctz (VI). Complexes are studied by the methods of chemical and X-ray powder diffraction analysis, thermogravimetry and IR-spectrometry. The structure of the synthesized complexes is set by the comparative analysis of the results of research of compounds I-VI and before structurally characterized 1-hydroxyethylenediphosphonategermanate of nicotinic acid Nic (VII). Catalytic activity of Ge02, H4Oedph and complex I in reaction of polycondensation of maleinic anhydride with ethyleneglycol is studied. |
