Controlled Degradation of a Ligand-Deficient Complex: From [{Cd(C6F5)(STrt)}4] to [{Cd(C6F5)(STrt)}3(OH)]− and [Cd(C6F5)(STrt)2]− (Trt = Triphenylmethyl)

✦ Synopsis

Bis(pentafluorophenyl)cadmium, [Cd(C 6 F 5 ) 2 ], reacts with equimolar amounts of triphenylmethanethiol, TrtSH, in toluene to give [{Cd(C 6 F 5 )(STrt)} 4 ] и 1.5 tol (1). The cuboidal complex of 1 has been transformed into the heterometallic cuboidal complex [{Cd(C 6 F 5 )(STrt)} 3 (OH)K(THF) 3 ] (2) by reaction with KOH in tetrahydrofuran. In the presence of 18-crown-6, the compound [K(18-crown-6)(THF) 2 ][{Cd(C 6 F 5 )-(STrt)} 3 (OH)] и THF (3) has been obtained instead of 2. X-ray structure analysis shows the anion of 3 to be an incomplete cuboidal complex, which alternatively can be described as a cyclic trimer of the {Cd(C 6 F 5 )(STrt)} unit stabilized by a µ 3hydroxo ligand. The compound [K(18-crown-6)(THF) 2 ]-

The nickel complex 2 Ni shows reactivity about 10 3 times greater than that of the cobalt analogue 2 Co . The oxidation ability of the M III (m-O) 2 M III core should be affected by the hindered Tp R ligand system, which can stabilize the 2 oxidation state of the metal centers.
