|Abstract:||A series of square-planar complexes [MLCl]ClO4 (M=Pd(II), Pt(II); L=bis(3-(diphenylphosphino)propyl)sulfide (psp), bis(3-(diphenylarsino)propyl)sulfide (asa)) have been prepared and characterized. The X-ray crystal structures of two of them have been determined: [Pd(psp)Cl]ClO4, P21/c, a=12.519(2), b=15.766(2), c=16.501(2) Å, β= 105.22(1)°, Z=4; and [Pt(asa)Cl]ClO4, P2]/ c, a= 12.583 (5), b=16.007(6), c=16.549(6) Å, β= 104.89(3)°, Z=4. In both structures, there is a conformational disorder between the chair and skew-boat orientation in one of the two six-membered chelate rings. The C-H-⋯-O hydrogen bond between the hybrid ligand and the perchlorate counter ion that induces the conformational disorder is discussed.|
