抄録

The reactions of 2-phenylbenzothiazoline with [M(CH3COO)2]·4H2O (M = Co(II) and Ni(II)) afford the complexes [M(phbt)2 ] (phbt = 2-(phenylmethyleneamino)benzenethiolato) via a ring opening reaction of 2-phenylbenzothiazoline. Spectroscopic data indicate that the cobalt and nickel atoms occupy a tetrahedral and a square planar N2S2 environment, respectively. The single crystal X-ray structure of [Ni(phbt)2] is redetermined and this complex shows a monohelical geometry. Crystal data: [Ni(phbt)2], monoclinic, C2/c, a = 23.065(4); b = 6.924(2); c = 13.809(2) Å; β = 102.64(1)°; V = 2152.0(9) Å3; Z = 4, R = 0.052 (Rw = 0.050). The toluene solution of [Co(phbt)2] and that of [Ni(phbt)2] lead to the complexes [Co(ddbt)] and [Ni(ddbt)] (ddbt = bis-2,2′-(1,2-diphenylethylenediimine)benzenethiolato) through the carbon–carbon bond formation, respectively. The structural features of [M(ddbt)] (M = Co and Ni) point clearly to the neutral dithiolene-like charge distribution. These complexes [M(ddbt)] have the same chemical compositions as the starting complexes [M(phbt)2], and both can be correlated in a new valence isomerism. Crystal data: [Co(ddbt)], monoclinic, P21/n, a = 8.573(2); b = 24.486(3); c =10.771(1) Å; β = 102.08(2)°; V = 2211.0(9) Å3; Z = 4, R = 0.056 (Rw = 0.048); [Ni(ddbt)], monoclinic, P21/n,a = 8.631(10); b = 24.365(19); c = 10.798(4) Å; β = 102.69(6)°; V = 2215.2(33) Å3; Z = 4, R = 0.078 (Rw = 0.075).
