The 1-D chain coordination complex of {[Mn2(HCAM)3(H2bipy)]·5H2O}n(H3CAM=4-hydroxypyridine-2,6-dicarboxylic acid,bipy=4,4′-bipyridine) has been synthesized by the reaction of 4-hydroxypyridine-2,6-dicarboxylic acid,4,4′-bipyridine and manganese carbonate under hydrothermal conditions,and its crystal structure was determined by X-ray diffraction method.The crystal belongs to the monoclinic system,space group P21/n with a=10.110(2),b=20.159(4),c=17.861(4) ,β=99.67(3)°,V=3.5884(12) nm3,Mr=901.47,Z=4,Dc=1.669 g·cm-3,μ=0.798 mm-1,F(000)=1840,the final R=0.0713 and wR=0.1853.The complex forms a 1-D chain bridged by HCAM,protonated 4,4-bipyridines link the 1-D chains to construct 2-D networks via N-H…O hydrogen bonds,and networks are further extended via π-π stacking and hydrogen bonds into 3-D supramolecular framework.

The 1-D chain coordination complex of {[Mn2 (HCAM) 3 (H2bipy) · 5H2O} n (H3CAM = 4-hydroxypyridine-2,6- dicarboxylic acid, bipy = 4,4’-bipyridine) has been synthesized by the reaction of 4-hydroxypyridine-2,6-dicarboxylic acid, 4,4’-bipyridine and manganese carbonate under hydrothermal conditions, and its crystal structure was determined by X-ray diffraction method. The crystal belongs to the monoclinic system, space group (2), b = 20.159 (4), c = 17.861 (4) β, β = 99.67 (3) °, V = 3.5884 (12) nm3, Mr = 901.47, Z = 4, Dc = 1.669 g cm-3, μ = 0.798 mm-1, F (000) = 1840, the final R = 0.0713 and wR = 0.1853. The complex forms a 1-D chain bridged by HCAM, protonated 4,4- bipyridines link the 1-D chains to construct 2-D networks via NH ... O hydrogen bonds, and networks are further extended via π-π stacking and hydrogen bonds into 3-D supramolecular framework.
