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....
HPAs exhibit wide range of molecular sizes, compositions, and structures. One of the great advantages of HPAs is that their catalytic properties can be easily tuned by changing the constituent metal components such as counter-cation, central heteroatom, or framework polyatom [3]. For example, ...
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 ...
The asymmetric unit of all prepared dihydrates consists of one half of the [V10O28]6– anion with Ci symmetry lying on an inversion centre, one [M(H2O)5(β-HAla)]2+ cation, one NH4+ cation, and two water molecules in general positions (Figure 2a). Figure 2. ADP representations of...
