| Abstract: | Reaction of a heptacoordinated Ca(II) compound [Ca(H2O)4(4-nba)2]
(4-nba = 4-nitrobenzoate) with 3,5-dimethyl-pyrazole (dmp) leads to the
formation of an eight coordinated Ca(II) compound, [[Ca(H2O)2(4-nba)2]·2dmp]n,
containing two coordinated water molecules, two unique 4-nba ligands and two
free dmp molecules in the lattice. The μ2-bridging tridentate
binding mode of the unique 4-nba ligands results in the formation of a
one-dimensional (1-D) coordination polymer. The title compound exhibits
enhanced fluorescence emission. An analysis of the six different bridging
binding modes of the 4-nba ligand in twenty two different structurally
characterized 4-nitrobenzoate compounds is described. |
