The solvothermal reaction of H3dhpmc (H3dhpmc = 2, 4-dihydroxypyrimidine- 5-carboxylic acid), CuCl2·H2O and NaVO3 results in the formation of a discrete mononuclear Cu(Ⅱ) complex [Cu(H2dhpmc)2]·2H2O. It crystallizes in monoclinic system, space group P21/c with a = 5.0497(9), b = 10.0196(6), c = 13.715(2) (A。）, β = 96.237(1)°, V = 689.8(2) (A。）3, Z = 2, Dc = 1.973 g/cm3, μ = 1.654 mm-1, F(000) = 414, R = 0.0736 and wR = 0.1351. Each Cu(Ⅱ) is coordinated to four oxygen atoms of two 2, 4-dihydroxypyrimidine-5-carboxylic acid ligands in the equatorial position and two oxygen atoms of two water molecules in the axial position to form an axially elongated octahedral geometry. The title complex is further linked into a three-dimensional structure through the weak interactions of hydrogen bonds between the oxygen atoms and the nitrogen atoms.
