摘要： Zn(C4H4O4) prepared by dissolving 0.483 g (1.41 mol) of Zn3(OH)4CO3·H2O and 0.5 g (4.23 mol) of C4H6O4 in 50 mL of H2O followed by slow evaporation at room temperature crystallizes in the monoclinic space group C2 with the cell parameters a=0.757　9(1) nm, b=0.597　6(1) nm, c=0.626　5(1) nm, β=108.45(1)°, V=0.269　17(7) nm3, Dx=2.239g/cm3, Z=2 and the final R(Fo)=0.039 and wR(FO2)=0.088 for 396 reflections ［FO2≥2σ(FO2)］. In the crystal structure unit, each Zn is tetrahedrally coordinated by four O atoms from four (C4H4O4)2- anions, each of which, in turn, bridges four Zn atoms to build up a 3D3∞［Zn(C4H4O4)4/4］ network. The thermal analyses indicate that Zn(C4H4O4) is stable below 420 ℃.
