Abstract
Abstract The structure of dibromobis(triphenylphosphine oxide) copper(II) has been determined by a single-crystal X-ray diffraction study. The compound crystallizes as orthorhombic crystals (a = 17.193(6) A, b = 10.226(4) A, and c= 19.052(4) A) of space group Pca21, with four molecules per unit cell (ϱobs = 1.55(2)g cm−3, ϱcalc = 1.55g cm−3. The structure was solved from Patterson and electron density maps and refined by least-squares methods to a conventional R value of 0.062 for 1283 independent, non-zero reflections. The coordination about copper is a slightly elongated tetrahedron with CuBr distances of 2.320(3) A and 2.302(2) A and CuO distances of 1.91(1) A and 1.96(1) A; the CuOP angels are 144.0(9)° and 154.8(7)°.
