In calitate de precursor s-a sintetizat compusul complex [Zn2(DAnH2)2(1,3bdc)2(DMF)4]∙2DMF∙MeOH·1.5H2O (1) (DanH2 – dianilinglioximă, 1,3-bdc – dianion al acidului 1,3-benzendicarboxilic). În mediu de dimetilsulfoxid complexul din 1 se transformă într-un polimer coordinativ 3D - {[Zn2(1,3-bdc)2(DMSO)2(H2O)]∙3DMSO}n (2). Pentru 1 şi 2 au fost inregistrate spectrele 1H şi 13C RMN, care evidentiază substituirea moleculelor de DAnH2 si DMF prin DMSO si apa, coordinate monodentat. Studiul cu raze X a demonstrat obtinerea compusului 2 de tip polimer coordinativ, fapt cauzat de funcţia punte a 1,3-bdc, spre deosebire de complexul din 1 binuclear centrosimetric, in care pozitiile terminale sunt blocate de DAnH2. Poliedrele de coordinare ale ambilor ioni de metal în 1 reprezintă octaedre distorsionate similare cu nod coordinativ ZnN2O4, pe când în 2 au fost depistate două tipuri – octaedric (ZnO6) şi tetraedric (ZnO4).

The complex compound [Zn2(DAnH2)2(1,3-bdc)2(DMF)4]∙2DMF∙MeOH·1.5H2O (1) (DanH2 – dianilineglyoxime, 1,3-bdc – 1,3-benzenedicarboxylic acid dianion) was synthesized as a precursor, then converted in dimethyl sulphoxide medium into a 3D coordinate polymer-{[Zn2(1,3bdc)2(DMSO)2(H2O)]∙3DMSO}n (2). The structure of complexes 1 and 2 were proved by 1H and 13C NMR spectra, which show the substitution of DAnH2 and DMF molecules by coordinated monodentate DMSO and water. The X-ray study confirmed the molecular structure of compound 2 as the coordinate polymer type, fact caused by the bridge function of 1,3-bdc, as opposed to the complex of 1 binuclear centrosimetric, in which the terminal positions are blocked by DAnH2. The coordinating polyhedra of both metal ions in 1 represent distorted octahedral similar to the coordinating node ZnN2O4, while in 2 were found two types - octaedric (ZnO6) and tetrahedric (ZnO4).
