Abstract:
The binuclear title complex, [Cu2I2(C26H24P2)2(C5H12N2S)2], lies about an inversion centre. The Cu(I) atom displays a distorted tetra-hedral coordination geometry defined by one S atom of an N,N'-di-ethyl-thio-urea ligand, two P atoms derived from two bridging 1,2-bis-(di-phenyl-phosphan-yl)ethane (dppe) ligands and one iodide ion. The dppe ligand bridges two symmetry-related Cu(I) ions, forming a 10-membered Cu2P4C4 ring. An intra-molecular N-H⋯I hydrogen bond is noted. In the crystal, N-H⋯I hydrogen bonds link complex mol-ecules into layers parallel to (-101).

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,...
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.
CFT focuses on...
02:42Ionic 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...
02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
