A new coordination polymer [Mn(3,5,6-tcpa)2(2,2′-bipy)]n (1) has been synthesized by the hydrothermal reaction of manganese sulfate hydrate with 3,5,6-trichloropyridine-2-oxyacetic acid (3,5,6-Htcpa) and 2,2′-bipyridine (2,2′-bipy) coligands. The x-ray single-crystal diffraction anal. shows that the MnII center is in deformed octahedral geometry bonded by two pyridyl nitrogen atoms of 2,2′-bipy mol. and four carboxy oxygen atoms of four different 3,5,6-tcpa- ligands. The 3,5,6-tcpa- anions play as bidentate bridging-μ2 linkers and connect neighboring MnII ions together to form the 1D double-stranded chain structure of 1, which displays interesting chair form [Mn2(COO)2] eight-membered rings. 1 Is further assembled into 3D network by the co-effects of π···π stacking and Cl···Cl halogen bonds interactions. In addition, the magnetic characterizations indicated weak antiferromagnetic coupling between MnII centers for 1.
