A new Co(II) compound, namely [Co(CH 3 O-H 2 Ip)(Bip)] n ( I ) (CH 3 O-H 2 Ip = 5-methoxylisophthalic acid and Bip = 3,5-bis(imidazole-1-yl)pyridine), has been synthesized through combination of CH 3 O-H 2 Ip, Bip and Co(II) acetate under hydrothermal condition and structurally characterized by IR spectroscopy, elemental analysis and single-crystal X-ray diffraction (CIF file CCDC no. 977220). It crystallizes in triclinic, space group P 1̅ with a = 9.764(6), b = 10.106(6), c = 11.673(7) Å, α = 104.12970°, β = 100.601(7)°, γ = 105.324(7)°, V = 1038.6(11) Å 3 , C 20 H 16 CoN 5 O 5 , Mr = 465.31, Z = 2, ρ calcd = 1.488 g/cm 3 , μ(Mo K α ) = 0.869 mm −1 , F (000) = 476, the final R = 0.0652 and wR = 0.1530. The X-ray analysis demonstrates that compound I exhibits a 2D + 2D polyrotaxane (4, 4) net network. Moreover, the thermal analysis of compound I has also been investigated.
