SYNTHESIS AND COMPREHENSIVE STUDY OF HETERONUCLEAR Ge(IV) – 3d METAL COMPLEXES WITH ETHYLENEDIAMINETETRAACETIC ACID AND 2,2ʼ-BIPYRIDINE
Synthetic approach have been developed, and different-metal coordination compounds [M(bipy)2{Ge(OH)(μ-Edta)}2]×nH2O (H4Edta is ethylenediaminetetraacetic acid, bipy is 2,2’-bipyridine, M = Mn(II), n=5 (1); Co(II), n=7 (2); Ni(II), n=7 (3); Cu(II), n=4 (4); Zn(II), n=5 (5)) have been prepared, their...

| description | Synthetic approach have been developed, and different-metal coordination compounds [M(bipy)2{Ge(OH)(μ-Edta)}2]×nH2O (H4Edta is ethylenediaminetetraacetic acid, bipy is 2,2’-bipyridine, M = Mn(II), n=5 (1); Co(II), n=7 (2); Ni(II), n=7 (3); Cu(II), n=4 (4); Zn(II), n=5 (5)) have been prepared, their comprehensive characterization has been carried out using modern physicochemical methods (elemental analysis, IR spectroscopy, mass spectrometry, and thermogravimetry), and structural features of new complexes have been determined. The synthesised complexes were found to be heteronuclear. The coordination polyhedron of the germanium(IV) remains analogous to that in the structurally characterized ethylenediaminetetraacetatogermanic acid, [Ge(OH)(HEdta)]·H₂O, adopting a distorted octahedral geometry formed by coordination to one hydroxyl group, three carboxylate oxygen atoms, and two nitrogen atoms of the Edta-ligand. The 3d metal center exhibits a coordination number of six, and it is bonded to two oxygen atoms of the carboxylate groups from two germanium-containing complex anions and four nitrogen atoms from two bipyridine molecules. |
