The title compound, chlorobis[1,2-ethanediylbis(diphenylphosphine)-P,P'](thiocarbonyl-C)technetium benzene solvate, [TcCl(C46H42P4)(CS)]·C6H6, was obtained as one of two Tc-containing products isolated from the reaction between CS2 and the electron-deficient complex [TcCl(dppe)2], where dppe is 1,2-ethanediylbis(diphenylphosphine). The structure exhibits an unusually short Tc-C distance [1.819 (6) Å], suggesting some multiple-bond character.

[TcCl(dppe)2] (100 mg) was added to a benzene (50 ml) solution containing
CS2 (0.2 ml) and triphenylphosphine (50 mg). This mixture was heated to
reflux for 2 min and then allowed to cool. Hexane was added to the solution
and then the mixture was allowed to stand. Over time, a mixture of orange and
yellow crystals were deposited. The yellow crystals proved to be
[TcCl(CS)(dppe)2]·C6H6.
All H atoms were placed in calculated positions, refined using a riding model,
and given an isotropic displacement parameters equal to 1.2 times the
equivalent isotropic displacement parameter of the atom to which they were
attached.

Special details top
Geometry. Bond distances, angles etc. have been calculated using the rounded
fractional coordinates. All e.s.d.'s are estimated from the variances of the
(full) variance-covariance matrix. The cell e.s.d.'s are taken into account in
the estimation of distances, angles and torsion angles |

Two new compounds were prepared during an examination of the reactivity of the 16-electron complex [TcCl(dppe)2], where dppe is 1,2-ethanediylbis(diphenylphosphine) (Burrell, Kubas & Bryan, 1994). Both a dithioformate complex, [Tc(S2CH)(dppe)2] (Bryan et al., 2001) and a thiocarbonyl complex [TcCl(CS)(dppe)2] were formed. The latter, (I), is the topic of this paper and is the first reported example of a Tc–thiocarbonyl complex.
The structure can be solved in P1 with Z = 1, but a high degree of correlation is observed, and the Cl and CS ligands are disordered (50:50) superimposed on each other. There is an apparent inversion centre at Tc, strongly suggesting that the correct space group is P1. When solved in P1, only half of the molecule makes up the asymmetric unit, with the metal ion located at the crystallographic inversion centre. The chloride and thiocarbonyl ligands are modeled with equal occupancy factors (50:50) at the same site of ligation on Tc, but are assumed to be different on either side of the inversion centre, as illustrated in Fig. 1. The Tc—C bond length is apparently quite short at 1.819 (6) Å, and may indicate some level of multiple bonding, although this bond distance may be affected by the disorder. The only published example of a Tc═C is the closely related [TcCl(CCHPh)Cl(dppe)2] (Burrell, Bryan & Kubas, 1994), which is 1.861 (9) Å. For comparison, Tc—CO bond lengths typically range from 1.88 to 2.00 Å, with a mean value of 1.93 Å (Allen & Kennard, 1993). Otherwise, the title complex is structurally quite similar to the isoelectronic [ReCl(CO)(dppe)2] (da Silva et al., 1998).
