Copper(I) and copper(II) complexes of polydentate phosphinoamines

摘要

Bidentate (PN) and tetradentate {P2N2} ligands stabilize copper(I) and copper(II) inside tetrahedral (Cu-I) and square planar (Cu-II) coordination spheres, to give [Cu(PN)(2)](+,2+) and [Cu(P2N2)](+,2+) complexes, which were characterized by Various spectroscopies. The crystal structure of [Cu(H(2)dppd)]BF4. MeCN (H(2)dppd=N,N'-bis[2-(diphenylphosphino)phenyl]-propane-1,3-diamine) was determined: monoclinic, space group P2(1), Z=4, a=11.483(4), b=13.516(6), c=24.224(9) Angstrom, beta=97.53(3)degrees, R=0.064 using 1897 observed reflections; Cu-P(1) 2.205(5), Cu-P(2) 2.213(4), Cu-N(1) 2.16(1), Cu-N(2) 2.14(1) Angstrom; P(1)-Cu-P(2) 125.1(2)degrees, N(1)-Cu-N(2) 95.9(4)degrees, P(1)-Cu-N(1) 87.4(3)degrees, P(2)-Cu-N(2) 87.8(3)degrees.
