Abstract:
The title compound, (C4H12N)[Cu3(CN)4] , crystallizes as a CuCN network solid, with di-ethyl-ammonium cations sandwiched between planar CuCN sheets comprised of trigonal planar and digonally coordinated CuI atoms bridged by linear CN groups to form 24-membered rings. The digonally coordinated CuI atoms and the di-ethyl-ammonium cations lie on separate crystallographic twofold rotation axes. One of the two independent CN groups has a 50:50 disordered orientation, while the other has one orientation favored due to a N-H⋯NC hydrogen bond between the di-ethyl-ammonium cation and the anionic CuCN framework. These hydrogen bonds link the sheets together into a three-dimensional network.

Ionic Crystal Structures
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...
Crystal 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,...
