Abstract:
In the title tetra-nuclear tin(IV) complex, [Sn(4)(CH(3))(8)(C(20)H(22)N(2)O(4))Cl(2)O(2)], there are three completely different tin-atom coordinations. One metal atom (site symmetry 2) adopts a distorted penta-gonal-bipyramidal SnC(2)N(2)O(3) coordination arising from the N,N',O,O'-tetra-dentate deprotonated Schiff base, two methyl groups in the axial sites and a μ(3)-O atom that also bonds to two further Sn atoms. Two symmetry-equivalent Sn atoms adopt very distorted SnC(2)O(4) arrangements that could be described as penta-gonal-bipyramidal with one equatorial vertex missing and the C atoms in the axial site. The final Sn atom (site symmetry 2) adopts an SnC(2)Cl(2)O trigonal-bipyramidal arrangement, with Cl atoms in the axial sites. As well as the two Sn atoms, one O atom lies on a twofold rotation rotation axis, and another is disordered about the axis. The terminal eth-oxy group is disordered over two sets of sites with equal occupancy.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
