Lewis-Base Adducts of Group 11 Metal(I) Compounds. XXV. Synthesis and Structural Properties of Tris(Triphenylphosphine)Copper(I) Perchlorate and Nitrate

Abstract

The compounds (PPh₃)₃CuOClO₃ and (PPh₃)₃CuONO₂(as its mono-ethanol solvate) have been characterized by single-crystal structure analysis. Crystals of the perchlorate are trigonal , P3, a 18.748(8), c 11.731(6)Ǻ, Z 3, and are isomorphous with the chloride and tetrafluoroborate structures. R was 0.062 for N_o = 1452 independent 'observed' reflections. Cu-P distances are 2.314(5), 2.313(7) and 2.317(8)Ǻ for each of the three molecules in the unit cell. P-Cu-P angles are 114.5(3), 114.4(3) and 115.6(3)°; Cu-O are 2.32(3), 2.23(3) and 2.23(3)Ǻ. Crystals of the nitrate are monoclinic, P2₁/n, a 14.875(5), b 23.349(7), c 14.141(7) Ǻ, β 91.73(3)°, Z 4. R was 0.045 for N_o = 4066. Cu-P distances are 2.312(2), 2.337(2) and 2.339(2)Ǻ; P- Cu-P angles are 114.15(7), 121.37(6) and 113.42(6)°. The nitrate group is monodentate with Cu-O, 2.174(4)Ǻ and Cu-O-N, 124.8(4)°.
