One new tri-nuclear nickel(II) coordination polymer, namely, [Ni₃(μ₃-O)(as-H₂bptc)₂(4,4′-bpy)₂(H₂O)₄]_n (H₄bptc = 2,3,3′,4′-biphenyl tetracarboxylic acid, and 4,4′-bpy = 4,4′-bipyridine) has been synthesised under hydrothermal conditions, and its structure and properties have been characterised by X-ray single-crystal and powder diffraction, infrared spectrum analysis, elemental analysis, thermogravimetric analysis and magnetic susceptibility analysis. The single-crystal diffraction results showed that complex crystallised in the C2/c monoclinic space group was a 3D structure with tri-nuclear Ni(II) secondary building units, in which metal cations were in octahedral coordination geometries. The powder X-ray diffraction indicated that the complex was a pure phase and thermal analysis showed the excellent thermal stability of the complex. Additionally, variable temperature (2–300 K) magnetic measurements indicated antiferromagnetic coupling or spin inclination behaviour in the Ni₃ core in the complex.
