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 monoelinic system,space group P21/n,C14H16ZnCl2N4O4,Mr=440.58,a=8.7893(7),b=24.978(2),c=9.2510(8) (A),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.
