Abstract:
The crystal structure of the title compound, bis-{μ-1,3-bis-[2-(di-phenyl-phosphan-yl)eth-yl]-1H-imidazole-κ2 P:P'}bis-[tri-chlorido-iron(III)], [Fe2Cl6(C31H31N2P2)2] or [{FeCl3}2(μ-PCHP)2] (PCHP = C31H31N2P2), consists of dinuclear complexes that are located about centres of inversion. The FeIII cation is in a distorted trigonal-bipyramidal coordination with three chloride ligands located in the trigonal plane and two P atoms of symmetry-related PCHP ligands occupying the axial positions. Within the centrosymmetric complex, a pair of intra-molecular C-H⋯Cl hydrogen bonds between aromatic CH groups and chloride ligands are found. Individual complexes are linked into layers parallel to (01) by inter-molecular C-H⋯Cl hydrogen bonds. No pronounced inter-molecular inter-actions occur between these layers. This arrangement leaves space for disordered solvent mol-ecules. Electron density associated with these additional solvent mol-ecules was removed with the SQUEEZE procedure in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18]. The given chemical formula and other crystal data do not take into account the unknown solvent mol-ecule(s).

SN2 Reaction: Kinetics
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a...
SN2 Reaction: Mechanism
The presence of the more electronegative halogen in the substrate creates a polarized carbon-halide bond. The halide pulls the electron cloud generating an electrophilic center at the carbon atom. Thus, the carbon atom carries a partial positive charge while the halide has a...
