Synthesis and crystal structure of a new three-dimensional Pb(II) hole structure coordination polymer based on based on 5-(3′,4′-Dicarboxylphenoxy)-isophthalic acid

A new Pb(II) polymer [Pb(dic)](n) 1 (H(4)dic = 5-(3 & PRIME;,4 & PRIME;-Dicarboxylphenoxy) -isophthalic acid) was synthesized. synthesized under hydrothermal conditions. The compound crystallizes in the Triclinic system, space group P-1 with a = 7.3690(2), b = 11.0528(3), c = 11.2613(3) angstrom, alpha = 62.4120(10)degrees, beta = 83.7290(10)?degrees, gamma = 75.6590(10)degrees, V = 787.58(4) angstrom(3), Z = 2, M-r = 774.60, D-c = 3.266 Mg/m(3), mu = 21.411 mm(-1), F(000) = 696, the final R = 0.0240 and wR = 0.0610 for 2923 observed reflections with I > 2 sigma(I). The compound presents a three-dimensional (3D) network extended by dic(4-) anions in which the dic(4-) anions employ a chelating coordination mode. Infrared spectroscopy, elemental analyses, thermogravimetric analysis and the single-crystal X-ray diffraction properties of 1 are also investigated.
