Abstract:
We have found that addition of a 2:1 ratio of the bulky ligand Li[N(mesityl)(SiMe(3))] to SnCl(2) yields Sn[N(mesityl)(SiMe(3))](2), which is found by X-ray crystallography to be monomeric in the solid state. Interestingly, the solid state structure of the stannylene exhibits a "minipocket" caused by the parallel arrangement of the phenyl rings. A 1:1 ratio of ligand to SnCl(2) affords the new chlorotin amide [Sn(mu-Cl)[N(mesityl)(SiMe(3))]](3), which adopts a unique trimeric structure in the solid state. The chairlike (Sn-Cl)(3) backbone shown here has not been seen previously in Sn-halide chemistry.

Structural 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 be...

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,...
