Five
manganese(II) coordination polymers with 2,3′,5,5′-biphenyl
tetracarboxylic acid (H4bptc) and five N-donor ancillary
ligands, {[Mn2(bptc)(2,2′-bipy)2]·2H2O}n (1), {[Mn2(H2bptc)2(phen)4]·6H2O} (2), {[Mn3(Hbptc)2(4,4′-bipy)4(H2O)4]·4H2O}n (3), {[Mn2(bptc)(1,4-biyb)2]}n (4), and {[Mn3(Hbptc)2(biip)2(H2O)2]}n (5) [2,2′-bipy
= 2,2′-bipyridine, phen = 1,10-phenanthroline, 4,4′-bipy
= 4,4′-bipyridine, 1,4-biyb = 1,4-bis(imidazol-1-ylmethyl)benzene,
biip = 3,5-bis(1-imidazol)pyridine], have been synthesized under hydrothermal
conditions. Complexes 1–5 were structurally
characterized by elemental analysis, infrared (IR) spectra, X-ray
single-crystal diffraction, and powder X-ray diffraction (PXRD). Complex 1 exhibits a 2D layered structure with a (3,6)-connected (43)2(46.66.83) topology.
Complex 2 shows a 0D structure and further stacks via
hydrogen-bonding interactions to give a 3D supramolecular architecture.
Complex 3 possesses a 3D structure with a 4-connected
(4.63.82)(44.62)(43.63) topology. Complex 4 displays
a 3D structure with a (4,5)-connected (4.52.6.7.8)(5.64.74.8)(4.52.62.74.8) topology. Complex 5 features a 3D structure with
a (4,5,6)-connected (42.64)(43.67)(42.68.73.82)
topology. Magnetic susceptibility measurements indicate weak antiferromagnetic
interactions between the Mn(II) ions in 1, 2, and 4.
