Abstract:
The title compound, [Cd3(C8H10O4)3(C12H9N3)2(H2O)2]n or [Cd3(chdc)3(4-PyBIm)2(H2O)2]n, was synthesized hydrothermally from the reaction of Cd(CH3COO)2·2H2O with 2-(pyridin-4-yl)-1H-benzimidazole (4-PyBIm) and cyclohexane-1,4-dicarboxylic acid (1,4-chdcH2). The asymmetric unit consists of one and a half Cd(II) cations, one 4-PyBIm ligand, one and a half 1,4-chdc(2-) ligands and one coordinated water molecule. The central Cd(II) cation, located on an inversion centre, is coordinated by six carboxylate O atoms from six 1,4-chdc(2-) ligands to complete an elongated octahedral coordination geometry. The two terminal rotationally symmetric Cd(II) cations each exhibits a distorted pentagonal-bipyramidal geometry, coordinated by one N atom from 4-PyBIm, five O atoms from three 1,4-chdc(2-) ligands and one O atom from an aqua ligand. The 1,4-chdc(2-) ligands possess two conformations, i.e. e,e-trans-chdc(2-) and e,a-cis-chdc(2-). The cis-1,4-chdc(2-) ligands bridge the Cd(II) cations to form a trinuclear {Cd3}-based chain along the b axis, while the trans-1,4-chdc(2-) ligands further link adjacent one-dimensional chains to construct an interesting two-dimensional network.

When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
