Syntheses, structures, and magnetic properties of two MOFs based on V-shaped carboxylate and flexible spacer ligand: From binuclear Co(II) with α-Po net to trinuclear Mn(II) with 416.611.8 topology

Syntheses, structures, and magnetic properties of two MOFs based on V-shaped carboxylate and flexible spacer ligand: From binuclear Co(II) with α-Po net to trinuclear Mn(II) with 416.611.8 topology
Two mixed-ligand coordination polymers, namely, {[Co(oba)(4-bpdb)]·CH3OH}n (1), and {[Mn3(oba)3(4-bpdb)(DMF)2]·4H2O}n (2) (H2oba=4,4′-oxybis-benzoate, 4-bpdb=1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene), were synthesized under solvothermal conditions. The structure of 1 possessed a three-fold interpenetrated 3D 6-connected pcu topology based on dimeric [Co2(COO)2]2− units. While 2 displayed a uninodal 3D 8-connected net with 416.611.8 topology based on trinuclear [Mn3(COO)6] subunits. Magnetic analyses indicate that both two compounds show weak antiferromagnetic interactions within binuclear Co(II) and trinuclear Mn(II) units.
