Abstract
AbstractThe MnII and CuII compounds of 3‐(2‐pyridyl)‐5,6‐diphenyl‐1,2,4‐triazine‐4,4′‐disulfonic acid (H2pdtd) were synthesized and systematically characterized. The metal‐organic framework (MOF) [Mn2(pdtd)2(H2O)4]n·5nH2O (1) was constructed by a solvothermal method preformed at 140 °C with methanol as the solvent, while [Cu(pdtd)(H2O)4]·H2O (2) was obtained by conventional solution chemistry conducted at 80 °C. Crystallographic analysis revealed that 1 has an acentric structure in which the MnII centers are linked via sulfonate groups and chelating nitrogen atoms within the pdtd ligands to give a rare noninterpenetrating (10,3)‐d framework with permanent helical cavities. Consequently, 1 exhibits nonlinear optical (NLO) activity, significant CO2 sorption, and magnetic coupling. In contrast, 2 is a mononuclear complex with coordinated water and lacks functional properties.
