Bis(ferrocenecarbaldehyde 4-methyl-thio-semicarbazonato-κN,S)zinc(II) methanol solvate
Abstract:
In the title compound, [Fe(2)Zn(C(5)H(5))(2)(C(8)H(9)N(3)S)(2)]·CH(3)OH, the dihedral angles between the substituted and unsubstituted cyclo-penta-dienyl rings are 89.34 (8) and 85.73 (9)°, respectively. The two Zn/S/C/N/N five-membered rings adopt envelope conformations, with the Zn(II) atom at the flap. Each methanol solvent mol-ecule is linked to three ferrocene groups via inter-molecular O-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds. The crystal structure is further consolidated by C-H⋯π inter-actions.

02:26Preparation and Reactions of Sulfides
Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.
03:45Formation of Complex Ions
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...
