Each cation is linked to four anions through O–H ··· N hydrogen bonds between the water ligand of the cation and one nitrogen atom of qdt ligand in the anion. Magnetic isolation of the Mn(II) centres in 3 is confirmed by magnetic susceptibility measurements....
In the crystal structures, the packing of the chains is further strengthened by a system of hydrogen bonds [in both (I) and (II)] and weak face-to-face π–π interactions [in (I)], forming three-dimensional metal–organic frameworks. The MnII cation in (I) has a trigonally ...
CN. Central Mn atom in the cation has a distorted octahedral coordination environment formed by six nitrogen atoms of three bi-dentate Phen ligands, average Mn-N bond length being 2.263(2) ? The anion has a chain-like structure built from three icosahedra sharing common vertices occupied by ...
