    Synthesis and structural characteristics of bis(citrate)germanates(IV) (Hbipy)2[Ge(HCit)2]∙2H2O and [CuCl(bipy)2]2[Ge(HCit)2]∙8H2O
    (2016) Seifullina, Inna Y.; Martsynko, Olena E.; Chebanenko, Olena Anatoliivna; Pirozhok, Olha; Dyakonenko, Viktoriya Volodymyrivna; Shishkina, Svitlana; Марцинко, Елена Эдуардовна; Марцинко, Олена Едуардівна; Сейфулліна, Інна Йосипівна; Сейфуллина, Инна Иосифовна
    The crystalline compounds (Hbipy)2[Ge(HCit)2]·2H2O (1) and [CuCl(bipy)2]2[Ge(HCit)2]·8H2O (2) (where H4Cit is citric acid, bipy is 2,2ʹ-bipyridine) were obtained for the fi rst time and their structures were determined by the single-crystal X-ray diffraction method. Compounds were characterized by IR spectroscopy, thermogravimetric (TGA) and elemental analyses. Both compounds are formed with complex bis(citrate)germanate anion and protonated 2,2’-bipyridine or [Cu(bipy)2Cl]+ as cations in compounds 1 and 2, respectively.

    Synthesis and structure of different-ligand and different-metal germanium(IV) complexes with malic acid and 1,10ʹ-phenanthroline
    (2017) Martsynko, Olena E.; Seifullina, Inna Y.; Chebanenko, Olena Anatoliivna; Afanasenko, Eleonora V.; Dyakonenko, Viktoriya Volodymyrivna; Shishkina, Svitlana; Марцинко, Олена Едуардівна; Сейфулліна, Інна Йосипівна; Афанасенко, Елеонора Вадимівна
    In the course o f the systematical research towards complex formation o f germanium (IV) with hydroxycarboxylic acids, we have previously synthesized and characterized structurally different-ligand and heteronuclear coordination compounds with citric, tartaric and xylaric acids. To continue the research as one o f the most interesting versatile polydentate ligand we have chosen the malic acid, which plays the key role in metabolism o f plants and animals, and is involved in many biochemical processes, e.g., the Krebs cycle.

    Synthesis, structure and investigation of germanium(iv) and copper(ii) complexes with malic acid and 1,10’-phenanthroline
    (2017) Seifullina, Inna Y.; Martsynko, Olena E.; Chebanenko, Olena Anatoliivna; Afanasenko, Eleonora V.; Dyakonenko, Viktoriya Volodymyrivna; Shishkina, Svitlana; Сейфулліна, Інна Йосипівна; Марцинко, Олена Едуардівна; Афанасенко, Елеонора Вадимівна
    Two crystalline compounds of germanium(IV) with malic acid (H3Mal) and 1,10’-phenanthroline (phen) - [Ge(HMal)2(phen)]·phen·2H2O (1) and [CuCl(phen)2][Ge(OH)(HMal)2] (2) were synthesized for the first time and characterized by elemental analysis, IR spectroscopy and thermogravimetric analysis. Using single crystal X-ray diffraction, two different forms of germanium were elucidated: Ge4+ (1) and hydrolyzed GeOH3+ (2) with a distorted octahedron and pyramid surrounding geometry, respectively.
