Five heterometallic mixed-ligand cation-anionic complexes perspective for creation of new effective nontoxic drugs [Fe(phen)(3)](2)[Sn-2(mu-Tart)(2)(H(2)Tart)(2)]center dot 2H(2)O (I), [Co(phen)(3)](2)[Sn-2(mu-Tart)(2)(H(2)Tart)(2)]center dot 8H(2)O (II), [Ni(phen)(3)[(2)[Sn-2(mu-Tart)(2)(H(2)Tart)(2)]center dot 2H(2)O (III), [Cu(phen)(3)1(2)[Sn-2(mu-Tart)(2)(H(2)Tart)(2)]center dot 2H(2)O (IV), [Zn (Phen)(3)](2)[Sn-2(mu-Tart)(2)(H(2)Tart)(2)]center dot 6H(2)O (V) with two types of ligands: ditopic polydentate tartaric acid (Tart) and cyclic bidentate 1,10-phenanthroline (phen), p-(Sn) and d-metals (Fe, Co, Ni, Cu, Zn) in their composition were synthesized. The studied complexes I-V are isostructural and contain complex anion [Sn-2(mu-Tart)(2)(H(2)Tart)(2)](4-), polyhedrons of two Sn atoms are octahedrons, that are formed by dimeric Sn-2(Tart(4-))(2) fragment and bidentate coordination of two terminal H(2)Tart(2)(-). All cations in I-V have similar structures [Me(phen)(3)](2+) with Me = Fe, Co, Ni, Cu, Zn. The present study compares electronic analogues Sn (IV) and Ge (IV) and reveals structural features of the novel tartratostannates and previously obtained tartratogermanates with the same compositional units.
