Abstract: High Resolution Image Download MS PowerPoint Slide Two Co(II) and Cd(II) coordination polymers, {(Me 2 bipy)[Co 5 (btc) 3 (Hbtc)(OH)]·2DMF·9H 2 O} n (CoMOF) and {(Me 2 bipy)[Cd 2 (μ 4 -btc) 2 ]} n ( OGU-2 ), were synthesized and characterized using IR spectroscopy, elemental analysis, and powder and single-crystal X-ray diffraction techniques. The Cd1 ion is seven-coordinated, adopting a distorted monocapped trigonal prismatic geometry (CdO 7 ). OGU-2 exhibits a 3D porous framework with a rare flu-3,6- C 2/ c topology. The framework contains one-dimensional channels along the c axis with dimensions of approximately 10 × 10 Å 2 . The photochromic behavior of OGU-2 was investigated, revealing excellent chromic properties in response to multiple external stimuli, including UV light, temperature, and organic amines. CoMOF, a coordination polymer reported previously, along with OGU-2, was evaluated as a catalyst for hydrogen gas production via the methanolysis reaction of NaBH 4 . The results demonstrated that these coordination polymers exhibited high catalytic activity for hydrogen production, comparable to the high values reported in the literature.
