Abstract The synthesis and the crystal and molecular structures of three metal(II) derivatives of lutidinic acid are presented (lutidinic acid=2,4-pyridinedicarboxylic acid=H22,4-pydc). Zn(2,4-pydc)(H2O)4]·H2O crystallizes in the monoclinic space group P21/c, with a=7.764(3), b=6.546(3), c=22.021(8) A; β=91.45(4)°; and Z=4. Na2[Zn(2,4-pydc)2(H2O)2]·8H2O crystallizes in P21/a, with a=7.070(2), b=13
