Two-dimensional silver(I) coordination polymer with twisted naphthalene rings

The silver(I) complex of octakis(cyclohexylsulfanyl)-naphthalene (ochsn), [Ag-4(ochsn)(CF3COO)(4)](CH2Cl2) (1), has been prepared and its molecular structure was determined by X-ray crystallography. In 1, the silver ion prefers a tetrahedral coordination geometry comprised of two S atoms from the ochsn molecules and the two O atoms from the counter anion then producing two-dimensional sheet structure. Interestingly, the naphthalene ring in the complex has large deviations from planarity and end-to-end twists on the order of 35degrees. In contrast, the central naphthalene ring of ochsn shows almost a planar structure in the solid state. (C) 2003 Elsevier Science B.V. All rights reserved.
