Abstract

The reaction of CoCl2, Habt (2-aminobenzenethiol), NaOMe and PBu3n (tributylphosphine) in an equimolar ratio under anaerobic conditions, followed by the addition of an excess of Li2S led to the triangular cluster complex Co-3(mu(3)-S)(abt)(3)(PBu3n)(3). It crystallizes in the triclinic space group P (1) over bar, with a=13.231(2), b=14.201(2), c=18.890(2) Angstrom, alpha=79.970(10)degrees, beta=87.560(10)degrees, gamma=67.040(1)degrees, V=3216.6(12) Angstrom(3) and Z=2. The molecule consists of three ''Co(abt)(PBu3n)'' units with the Co-3 plane capped by the bridging mu(3)-S atom to form an approximately equilateral triangle with an average Co-Co distance of 2.709 Angstrom. The cobalt atomslocated in distorted trigonal-bipyramidal environments are further bridged by mu(2)-S atoms from the three abt ligands and terminally coordinated by N and P donors. The cyclic voltammogram showed three quasi-reversible redox processes with E-1/2=0.79, -0.07, and -0.81 V, vs. SCE. The variable-temperature magnetic susceptibility measurements showedan antiferromagnetic exchange interaction within the triangular spin cluster.
