Synthesis and structure of heterometallic multiligand Ge(IV) - 3d-metals complexes with 1-hydroxyethane-1,1-diphosphonic acid and 1,10-phenanthroline
Abstrak
Synthesis methods were developed, five new coordination compounds were isolated and investigated: [M(phen)3]4[Ge6(μ-OH)4(μ-O)2(μ-hedp)6]*хСН3СООН*nH2O (M= Fe (1), x= 0, n= 20; Co (2), x= 2, n= 30; Ni (3), x= 2, n= 26), [Cu(phen)2(H2O)]2[Cu(phen)(H2O)3]2[Ge6(μ-OH)4(μ-O)2 (μ-hedp)6]*16H2O (4), [Zn(phen)2(H2O)2]2[Zn(phen)(H2O)4]2[Ge6(μ-OH)4(μ-O)2(μ-hedp)6]*18H2O (5), were Н4hedp - 1-hydroxyethane-1,1-diphosphonic acid, phen - 1,10-phenanthroline. It was found that the complexes belong to the cation-anion type, consisting of the hexanuclear complex anion, in which Ge atoms are connected by three types of bridging ligands (hydroxy-, oxo-, and 1-hydroxyethane-1,1-diphosphonate), and phenanthroline-containing cations of different compositions depending on the 3d-metal. Synthesized substances in crystals are organic-inorganic hybrid ensembles with three-dimensional networks formed by numerous intermolecular hydrogen bonds between complex cations, anions, and water of crystallization molecules.
