The monomeric cobalt-phosphite-thiolato complex [ Co (mpt)2 {P (OCH3 )3 }2 ] BF4 (Hmpt = 2-mercaptothiazoline) has been prepared and characterized by X-ray crystallography. The complex crystallizes in the monoclinic space group C2/c with a= 0.8078(5), b=2.6020(18), c=1.2191(7) nm, β= 99.38 (1)°, V= 2.528(3) nm3, and Z = 4. The structure comprises discrete cations [Co(mpt)2{P(OCH3)3}2.] + and anions BF4- , in which the cobalt (Ⅲ) atom is coordinated to two chelate mpt- and two as-oriented monodentate P(OCH3)3 ligands in a highly distorted octahedral geometry. The most distorted angles are S(2)-Co(1)-S(2a) of 162.23(10)° and N(1)-Co(1)-S(2) of 71. 47 (13)°, the latter is caused by the geometric constraint of the bidentate ligand mpt- . Cyclic voltammetry has been used to study the electrochemical behavior of the title complex on the R electrode in MeCN solution with 0.1 mol·L-1 of Bun4NBF4 as electrolyte. The results indicate that the title complex is unstable in MeCN.
