N2 - A zinc(II) compound [ZnCl2(mpcm)2] (1, mpcm = methyl-3-pyridylcarbamate) was prepared by solvothermal reaction and characterized by elemental analysis, IR spectroscopy, TGA and single-crystal X-ray diffraction. The crystal is of monoclinic system, space group p2 1/n, C14H16ZnCl2N4O 4, Mr = 440.58, a = 8.7893(7), b = 24.978(2), c = 9.2510(8) Å, β = 109.318(1)°, V= 1916.6(3) A°3, Z = 4, θ = 1.63∼25.20°, Dc = 1.527 g/cm3, μ = 1.585 mm-1, F(000) = 896, the final R = 0.0255 and wR = 0.0654 for 3080 observed reflections with I > 2σ(I). The zinc atom is four-coordinated by the pyridyl groups of two mpcm ligands and two chloride ions with a tetrahedral geometry. Two [ZnCl2(mpcm)2] subunits are held together by a pair of hydrogen bonds, forming a 32-membered macrocyclic dimer, which is further extended into a 3D tubular structure via hydrogen bonding.
