Solid state (31)P n.m.r., far-i.r. spectroscopy and single-crystal X-ray diffraction techniques have been used to characterize a new type of ionic copper(I) compound: a trigonal planar arrangement, with Cu-P 2.210(3), Cu-Br 2.367(2), 2.386(21) Angstroem and Br-Cu-Br 114.9(1) deg a strong band at 195 cm-1 assigned to the antisymmetric Cu-Br stretching mode of the CuBr2 unit, and a weaker band at 150 cm-1 assigned to the symmetric Cu-Br stretching mode.This assignment is supported by an approximate normal-co-ordinate analysis, and the resulting Cu-Br force constant is compared with values obtained in similar analyses of related bromocopper(I) complexes.The cross-polarization magic angle spinning (31)P n.m.r. spectrum shows a strong signal at 21 p.p.m. (relative to 85percent H3PO4) due to the cation, and a weaker quartet centred at -14 p.p.m. due to the co-ordinated PPh3 in the anion, with line spacings due to Cu-P coupling of 1.37, 1.69, and 1.92 kHz.
