A novel 2-D lead-containing hybrid compound, [(PbCl2)(μ-Pyz)1/2]n (Pyz = py- razine) 1, has been synthesized by the hydrothermal assembly of pyrazine with lead chloride. Elemental analysis and X-ray crystal structure analyses were carried out for the structural deter- mination and characterization of the title compound. Compound 1 crystallizes in orthorhombic, space group Ibam, with a = 19.5558(18), b = 7.1939(6), c = 7.5449(6) , V = 1061.44(16) 3, C2H2Cl2NPb, Mr = 318.14, Z = 8, Dc = 3.982 g/cm3, μ = 32.63 mm-1, F(000) = 1096.0, R = 0.0368 and wR = 0.0901 for 623 observed reflections (I > 2σ(I)).
