Abstract

Hydrothermal reactions of cobalt(II) salt with H₂CAM or H₂SDBA and HBTA in the presence of NaOH afford two interesting coordination polymers, Co₃(CAM)₂(BTA)₂ (1) and Co₃(SDBA)₂(BTA)₂ (2) (H₂CAM = camphoric acid, H₂SDBA = 4,4′-dicarboxybiphenyl sulfone, HBTA = benzotriazole), both of which have been structurally characterized by single-crystal X-ray, elemental analysis, infrared spectroscopy, and thermogravimetric analysis. Complexes 1 and 2 are isostructural and possess two-dimensional covalent network, comprising an unusual linear Co(II) chains of mixed T_d-O_h-T_d geometries. Temperature-dependent magnetic measurements indicate the existence of antiferromagnetic interactions in both 1 and 2.
