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 coordination polymers are reported: complex 1 possessed a threefold interpenetrated 3D 6-connected pcu topology based on dimeric [Co2(COO)2]2 − units, while 2 displayed a uninodal 3D 8-connected net with a 416.611.8 topology based on trinuclear [Mn3(COO)6] subunits. The magnetic properties of the compounds were explored.251
