Abstract

Orange-red (CuBr)₂P₈Se₃ was obtained from stoichiometric amounts of CuBr, P and Se by melting and subsequent annealing at 380°C for 1 month. The crystal structure was determined from single crystal X-ray data. (CuBr)₂P₈Se₃ crystallizes in the orthorhombic system, space group Pbcm (No. 57), with a=8.761(1)Å, b=11.957(1)Å, c=13.858(1)Å, V=1451.8(3)Å³, and Z=4. This compound consists of neutral P₈Se₃ cage molecules attached to Cu₂Br₂ rhombs. Vibrational spectroscopic data are reported for (CuBr)₂P₈Se₃ and for the homologous (CuI)₂P₈Se₃. The wavenumbers of the Cu-Br and Cu-I vibrational modes show an excellent correlation with the corresponding Cu-X bond lengths.
