Syntheses, crystal structures, and magnetic properties of metal-organic hybrid materials of Mn(II)/Co(II): three-fold interpenetrated alpha-polonium-like network in one of them
Three new 1,4-phenylenediacrylate bridged Mn(II) and Co(II) complexes with the molecular formulae {[Mn2(phen)4(H2O)2(ppda)]∙(ppda)∙2(H2O)}(1), {[Co(ppda)(dpyo)(H2O)3]∙4(H2O)}n (2), and {[Co(ppda)(bpe)]∙(0.5H2O)}n (3) [phen = 1,10-phenanthroline; ppda = 1,4-phenylenediacrylate; dpyo = 4,4´-dipyridyl...

| Sumario: | Three new 1,4-phenylenediacrylate bridged Mn(II) and Co(II) complexes with the molecular formulae {[Mn2(phen)4(H2O)2(ppda)]∙(ppda)∙2(H2O)}(1), {[Co(ppda)(dpyo)(H2O)3]∙4(H2O)}n (2), and {[Co(ppda)(bpe)]∙(0.5H2O)}n (3) [phen = 1,10-phenanthroline; ppda = 1,4-phenylenediacrylate; dpyo = 4,4´-dipyridyl N,N´-dioxide; bpe = 1,2-bis(4-pyridyl)ethane] have been synthesized and characterized by elemental analysis, IR spectra, single-crystal X-ray diffraction studies and low temperature magnetic measurements. Structural determination reveals that complex 1 is dinuclear, 2 is a 1D polymeric chain, while 3 is a three-fold interpenetrated α-polonium-like network. Hydrogen bonding interactions, formed by coordinated and/or lattice water molecules with ppda oxygen, and staking interactions of aromatic rings lead to a 3D supramolecular architecture in both complexes 1 and 2. Low temperature magnetic study shows antiferromagnetic coupling in all the complexes. In addition, their electronic and fluorescent spectral properties have also been investigated. |
