Chlorido(1-cyclo-pentyl-idene-4-ethyl-thio-semicarbazidato-κN,S)diphenyl-tin(IV)
Abstract:
The Sn atom in the title compound, [Sn(C(6)H(5))(2)(C(8)H(14)N(3)S)Cl], is penta-coordinated with a trigonal-bipyramidal coordination geometry. The 1-cyclo-pentyl-idene-4-ethyl-thio-semicarbazidate (cpetsc) ligand coordinates through the S atom and the N atom bonds to the cyclo-pentyl group, forming a five-membered ring with the Sn center. The chloride ligand and the coordinated N atom are in axial positions. In the crystal structure, inter-molecular N-H⋯Cl hydrogen bonds form chains along [101].

Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...

Halogenation of Alkenes
Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
