Abstract:
The mol-ecular components of the title salt, [Cu(C4H11NO2)2](C8H4O4), are one Cu(II) cation O,N,O'-chelated by two tridentate 2-[(2-hy-droxy-eth-yl)amino]-ethanol ligands, and a terephthalate counter-dianion, located about a centre of inversion. The complex Cu(II) cation is located about a centre of inversion and shows typical Jahn-Teller distortion, with two short Cu-O and two short Cu-N bonds in the equatorial plane and two long Cu-O bonds to the axial atoms. The cations are arranged in sheets parallel to (100), with the centrosymmetric terephthalate anions located between the sheets. Each anion is the acceptor of four O-H⋯O and two N-H⋯O hydrogen bonds, forming a three-dimensional network structure.

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...

Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
