Hydrothermal reaction of benzene-1,2,4,5-tetracarboxylic(Btec) dianhydride with La2O3 lead to a new organometallic compound, [La2(betc)(Hbtec)(H2O)3][HCONH(CH3)
Two new supramolecular complexes [MnL(H2O) 4](1) and [ZnL(H2O) 5]·0.25H2O(2) (H2L = 5-carboxy-1-carboxymethyl-2-oxidopyridinium) have been synthesized and
