Аннотация:Reactions of vanadyl sulfate (VOSO4•3H2O) with dimethylmalonic (H2Me2mal =
= C3H6(CO2H)2), cyclobutane-1,1-dicarboxylic (H2cbdc = C4H6(CO2H)2), or butylmalonic
acid (H2Bumal = C4H10(CO2H)2) and Li2CO3 in a ratio of 1 : 2 : 2 afforded novel coordination
polymers of similar compositions ([Li2(VO)(Me2mal)2]n (1), [Li2(VO)(Me2mal)2(EtOH)(H2O)]n (2), [Li4(VO)2(cbdc)4(H2O)7]n (3), and [Li2(VO)(Bumal)2(H2O)5.5]n (4)) but different
structures. The crystal structures of the compounds containing the Me2mal2– and Bumal2–
anions depend on the solvent nature.
