EnglishThree new coordination polymers of manganese(II) of formulae [Mn3(phen)2(phdac)3]2H2O (1), [Mn(4,40-bipy)(H2O)4](cbprop)(2) and [Mn(2,20-bipy)(4-nph)(H2O)2]2 (3) (phen = 1,10-phenanthroline, 4,40-bipy = 4,40-bipyridine, 2,20-bipy = 2,20-bipyridine, H2phdac = 1,4-phenylenediacetic acid, H2cbprop = 4-carboxybenzenepropanoic acid and H2nph = 4-nitrophthalic acid) have been synthesized and structurally characterized by X-ray single-crystal diffraction analysis. The metal complexes possess 2D (1), 1D (2) and 0D (3) dimensionalities. In each case, the crystal packing shows three-dimensional architecture by means of p–p interactions and/or hydrogen bonding supported by coordinated and lattice water molecules. The emission spectra show metal-perturbed intra-ligand p*–p charge transfer transitions for 1 and p*–p and p*–n charge transfer transitions for 3.

| Abstract: | Three new coordination polymers of manganese(II) of formulae [Mn3(phen)2(phdac)3]2H2O (1), [Mn(4,40-bipy)(H2O)4](cbprop)(2) and [Mn(2,20-bipy)(4-nph)(H2O)2]2 (3) (phen = 1,10-phenanthroline, 4,40-bipy = 4,40-bipyridine, 2,20-bipy = 2,20-bipyridine, H2phdac = 1,4-phenylenediacetic acid, H2cbprop = 4-carboxybenzenepropanoic acid and H2nph = 4-nitrophthalic acid) have been synthesized and structurally characterized by X-ray single-crystal diffraction analysis. The metal complexes possess 2D (1), 1D (2) and 0D (3) dimensionalities. In each case, the crystal packing shows three-dimensional architecture by means of p–p interactions and/or hydrogen bonding supported by coordinated and lattice water molecules. The emission spectra show metal-perturbed intra-ligand p*–p charge transfer transitions for 1 and p*–p and p*–n charge transfer transitions for 3. |
