Synthesis and Crystal Structures of the Coordination Polymers Pb(PYTAC)2 and Pb2(PYTAC)3(NO3) (PYTAC=2-(pyridin-4-yl)thiazole-5-carboxylate)

Two lead coordination compounds, Pb(PYTAC)(2) (1), and Pb(PYTAC)(2)(NO3) (2), were grown as single crystals via hydrothermal synthesis (PYTAC = 2-(4-pyridyl) thiazole-4-carboxylate). Both compounds have been identified via single crystal X-ray diffraction. Coordination polymer 1 crystallizes in a triclinic space group P-1 (a = 5.5097(4) angstrom, b = 7.2822(5) angstrom, c = 11.3134(8) angstrom, alpha = 103.5580(10)degrees, beta = 99.4330(10)degrees gamma, c = 97.1050(10)degrees), and forms 2-D layers parallel to the crystallographic (ac) plane. Coordination polymer 2 crystallizes in a triclinic space group P-1 (a = 9.8102(5) angstrom, b = 10.5972(6) angstrom, c = 14.8076(8) angstrom, alpha = 91.9350(10)degrees, beta = 100.8050(10)degrees, gamma = 103.1350(10)degrees), and forms an infinite 1-D chains along the a axis.
