Two new mixed-ligated metal phosphonates,M_2(pbtcH)(phen)_2(H_2O)_2[M(II) = Co(1),Ni(2)](pbtcHr,= 5-phosphonatophenyl-1,2,4-tricarboxylic acid,phen = 1,10-phenanthroline),have been synthesized and characterized.Both show one-dimensional double chain structures,where the M(phen)(H_2O) moieties are chelated and bridged by pbtcH~(4-) through the carboxylate and phosphonate oxygen atoms.The chains are connected by hydrogen bonding interactions and π-π stacking,forming a three-dimensional supramolecular structure.The IR and magnetic properties of the two compounds are also investigated.
Two new mixed-ligated metal phosphonates, M_2 (pbtcH) (phen) _2 (H_2O) _2 [M (II) = Co (1), Ni (2)] (pbtcHr, = 5-phosphonatophenyl- tricarboxylic acid, phen = 1,10-phenanthroline), have been synthesized and characterized. Show one-dimensional double chain structures, where the M (phen) (H_2O) moieties are chelated and bridged by pbtcH ~ (4-) through the carboxylate and phosphonate oxygen atoms. The chains are connected by hydrogen bonding interactions and π-π stacking, forming a three-dimensional supramolecular structure. IR and magnetic properties of the two compounds are also investigated.
