摘要

A new metal-organic hybrid compound?[Fe(O3C4)(COO)]·H2O I has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction. Rust crystals crystallize in the monoclinic system, space group I2/a, a = 6.9651(2) A, b = 8.12630(10) A, c = 19.4245(2) A, β = 92.6600(10)°;V = 1098.25(4) A3;Z = 2 and Dx =3.63g/cm3. The refinement converged into R = 0.042;Rw = 0.058. The structure, determined by single crystal X-ray diffraction, consists of a network of FeO6 centers, octahedral coordinated by btec (btec = 1,2,4,5-benzenetetracarboxylic acid) anions giving rise to a two-dimensional sheet structure. In the compound I,?[Fe(O3C4)(COO)]·H2O, the FeO6 group bridged by the 1,2,4,5-benzenetetracarboxyl anion exist in a unit cell, with each anion lying about an inversion centre. One of the FeO2 adistance [1.965(2)] significantly corresponds to the shortest distance as the other and the distances found in the axial direction of compound I.
