Abstract

Ionic macrocyclodimeric palladium(II) complex, [(dppp)Pd(m-pmps)] ₂(CF₃SO₃)₄ (dppp = 1,3-bis(diphenylphosphino)propane; m-pmps = 1,3-bis(3-pyridyl)-1,3-dimethyl-1,3- diphenyldisiloxane), was synthesized and its molecular structure determined by X-ray single crystallography. The complex has 19 rings consisting of one 20-membered metallamacrocycle, 2 six-membered metallacycles, 4 pyridyl groups, and 12 phenyl groups. The local geometry around palladium(II) approximates to a typical square planar arrangement with two cis phosphines (P-Pd-P = 90.54(7)°; N-Pd-N = 84.6(2)°; Pd-P = 2.259(2)Å, 2.270(2)Å Pd-N = 2.100(5)Å, 2.112(5)Å). The triflates were smoothly exchanged to produce [(dppp)Pd(m-pmps)]₂(X)₄ (X^- = (X^-=NO^-₃, ClO^-₄, BF ^-₄, PF^-₆, and SbF^- ₆ ; (X)₂=SO^2-₄ and MoO ^2-₄ ). According to 1H-NMR chemical shifts and conductivity measurements, the macrocyclodimer was sensitive to the Hoffmeister series of anions.
