Popis:	The cation-anionic coordination compounds based on the copper(II) complexes with Phen and tartratogermanate anions, [Cu(Phen)3]2[Ge2(OH)(HTart)(µ-Tart)2] · 11H2O (I) and [CuCl(Phen)2]4[{Ge2(OH)2(µ-Tart)2}Cl2] · 4Н2О (II), with different compositions and structures (CIF files CCDC nos. 1878102 (І) and 1878103 (ІІ)) are isolated for the first time from the GeO2–tartaric acid (H4Tart)–CuCl2–1,10-phenanthroline (Phen) system. The structures of compounds I and II contain the same bridging tartrate anions. A specific feature of compound I is the additional HTart3– anion, which does not perform the bridging function but is coordinated via the bis(chelate) mode, and the hydroxyl and carboxyl groups remain vacant. The dissociation of the carboxyl group results in the formation of the tartratogermanate anion with the charge –4.
