Orange-red (CuBr)(2)P8Se3 was obtained from stoichiometric amounts of CuBr, P and Se by melting and subsequent annealing at 380 degreesC for 1 month. The crystal structure was determined from single crystal X-ray data. (CuBr)(2)P8Se3 crystallizes in the orthorhombic system, space group Pbcm (No. 57), with a = 8.761(1) Angstrom, b = 11.957(1) Angstrom, c = 13.858(1) Angstrom, V = 1451.8(3) Angstrom(3), and Z = 4. This compound consists of neutral P8Se3 cage molecules attached to Cu2Br2 rhombs. Vibrational spectroscopic data are reported for (CuBr)(2)P8Se3 and for the homologous (CuI)(2)P8Se3. The wavenumbers of the Cu-Br and Cu-I vibrational modes show an excellent correlation with the corresponding Cu-X bond lengths. (C) 2004 Elsevier B.V. All rights reserved.
