Abstract
Two coordination polymers (CPs) [M(HCOO)2(TPB)(H2O)2]n (M = Co, 1; Ni, 2; TPB = 1,3,5-tri(pyridin-4-yl)benzene) have been successfully synthesized under solvothermal conditions and characterized. Single-crystal X-ray diffraction analyses showed that CPs 1–2 are three-dimensional (3D) supermolecules formed with two adjacent sets of mirror-symmetric zigzag-shaped polymer chains by hydrogen bonding. The photodegradation studies demonstrated that 1–2 showed high-efficiency degradation with a rate of 72.3 % and 81.3 % for RhB under ultraviolet irradiation within 120 min, and the mechanism study revealed that both two effective oxidants O2– and OH co-participated during the degradation. Furthermore, magnetic study indicated that 1–2 exhibited weak antiferromagnetic behaviour and presented easy-plane anisotropy with D = 8.64, 7.40 cm−1 respectively.
