(T-4)-Dichlorobis(triphenylphosphine)cobalt

The synthesis of [Ni(L)][CoCl4] was carried out by a modifiedprocedure [24]. To 20 mL solution of [Ni(L)(ClO4)2] (0.94 g, 2 mmol)in methanol, was added dropwise CoCl2(PPh3)2 (1.31 g, 2 mmol)solution in 20 mL THF to obtain a green solution. The mixture wasrefluxed for 8 h, affording a green powder that was filtered, washedwith acetonitrile, ether and recrystallized from 1:1 mixture ofwater and methanol. Yield 83%. Anal. Calc. for C9H22Cl4N6NiCo: C, 22.81; H, 4.68; N, 17.74; Ni, 12.39. Found: C, 22.73; H, 4.34; N, 17.94;Ni, 12.53.General procedure: All the new metal complexes were prepared according to the following general procedure. A warm ethanol solution (10 mL) containing H3L1-2Cl (1 mmol) was added to ethanol solution (10 mL) of [CoCl2(PPh3)2] (1 mmol).The resulting reddish solution was refluxed for 5 h. Dark red colored crystalline powder was obtained on slow evaporation. They were filtered off, washed with cold ethanol, and dried under vacuo.General procedure: All the new metal complexes were prepared according to the following general procedure.
