Coordination Polymers Based on Oxovanadium(IV) Butylmalonate Fragments and Potassium, Magnesium, and Cadmium Cations

The data on the synthesis and study of the crystal structure of compounds {[K2Mg2(VO)3(Bumal)6(H2O)15] · 2H2O}n (I) and {[Cd(VO)(Bumal)2(H2O)5] · H2O}n (II) are presented. According to X-ray diffraction, these compounds are formed by the anionic fragments [VO(Bumal)2(H2O)]2– with oxovanadium(IV) and two butylmalonate anions (H2Bumal is C5H10(COOH)2) coordinated via the chelate mode. In the crystals of compound I (CIF file CCDC no. 1911220), the [VO(Bumal)2(H2O)]2– anionic fragments are bound to each other by the K+ and Mg2+ cations into the 2D polymeic structure. In compound II (CIF file CCDC no. 1033008), these fragments are bound by the Cd2+ cations to form the 1D coordination polymer.
