Abstract

Δ-RR,∧-SS-[Co(acac)₂(rac(P)-L)]⁺ and [Co(acac)₂(raeso(P)-L)]⁺ were obtained by reaction of [Co(acac)₃] (acac=2, 4-pentanedionate ion) with 5, 8-diphenyl-5, 8-diphospha-2, 11-dithiadodecane (L) in 1:1 molar ratio in dichloromethane in the presence of active charcoal, no Δ-SS,∧-RR isomer of the rac(P)-L complex being formed. Five-coordinate [Ni(rac(P)-L)₂]²⁺ and [Ni(raeso(P)-L)₂]²⁺ were yielded by reaction of Ni(II) and L in 1:2 molar ratio in methanol, and the molecular structure of less soluble [Ni(rac(P)-L)₂](BF₄)₂ was determined by X-ray analysis. Crystal data: monoclinic, space group P2₁/n, a=17.136(3), b=20.134(5), c=14.106(3) Å, β=93.30(2)°, V=4859(2) Å³, Z=4, R=0.089 for 8001 reflections. The Ni atom is surrounded square pyramidally by four P atoms in the basal plane and one S atom at the apical position with distances of the Ni-P: 2.214(2)-2.234(2) Å and the Ni-S: 2.603(2) Å. Both [Ni(rac(P)-L)₂]²⁺ and [Ni(meso(P)-L)₂]²⁺ in CH₂Cl₂ solutions exchange four -SCH₃ groups at the apical positin on the NMR time scale. White [Cu(rac(P)-L)]BF₄ was precipitated selectively by reaction of Cu(BF₄)₂ • 6H₂O and L in 1:1 molar ratio in ethanol.
