Becker Comment Metal (Ni, Pd) complexes in which the atom is coordinated by a S,S-chelating dithiocarbamate, one halogenide and one phosphine have been investigated and used to obtain compounds with a sulfur rich kernel arising from the presence of two different S-donor ligands (Darkwa et al., 1999; Pastorek et al., 1999; Reger & Collins, 1995). Several structures of such species are stored in the Cambridge Structural Database (CSD-2007, Allen 2002). Recently, we reported the synthesis of [Ni{S 2 CN(CH 2 ) 4 }(Cl)(PPh 3 )] (Kropidłowska, Janczak et al., 2007) solvated by a chloroform molecule, which interacts with the complex by a weak C H S hydrogen bond. The structure of homologous hemisolvated [Ni{S 2 CN(CH 2 ) 4 }(Br)(PPh 3 )] has also been reported (Pastorek et al., 1996). In the present paper we describe the structure of another nickel(ii) complex - (1-pyrrolidinylcarbodithioato-S,S') -chlorido- (diphenylethylphosphine)nickel(ii), [Ni{S 2 CN(CH 2 ) 4 }(Cl)(PPh 2 Et)] (I) obtained by essentially quantitative metathesis of trans-dichloro-bis(diphenylethylphosphine)-nickel(ii) and bis(1-pyrrolidinylcarbodithioato-s,s')nickel(ii). The molecular structure of (I) with the atom numbering scheme is shown in Figure 1. In this compound the metal(ii) ion is four-coordinated within a typical square planar [NiClS 2 P] heterogeneous coordination sphere. The dithiocarbamate ligand acts as a bidentate chelate, coordinating to Ni via both S atoms and thus introducing a deformation of the coordination geometry. Atom S1 is located trans to the Cl ligand and atom S2 is trans to the diphenylethylphosphine ligand. Although (I) was obtained in the same manner as previously mentioned [Ni{S 2 CN(CH 2 ) 4 }(Cl)(PPh 3 )] it did not retain the solvent within its crystal structure, similarily to previously described [Ni{S 2 CN(C 4 H 8 O)}(Cl)(PPh 3 )] (Kropidłowska, Chojnacki et al., 2007). The schematic drawing of the crystal packing in (I) is presented in Figure 2. Experimental. Nickel chloride, NiCl 2 6H2 O (0.594 g, mol, purchased from POCh) was dissolved in 50 ml of methanol/water (10/1, v/v) and this solution was added dropwise to the ammonium salt of pyrrolidinylcarbodithioic acid C 4 H 8 NCS 2 NH 4 (0.82 g, mol, Fluka) dissolved in methanol/water. This mixture was stirred vigorously under argon atmosphere for ca 20 minutes, then filtered and the filtrate left for crystallization at 278 K. After a week the green crystalline product, namely Ni(S 2 CNC 4 H 8 ) 2 was collected. It was further dissolved (0.199 g, mol) in 10 ml of chloroform and mixed with solution of equimolar amount of NiCl 2 (PPh 2 Et) 2 (0.315 g). The mixture which turned into deep violet colour, was stirred for 10 minutes and then filtered. To the filtrate 10 ml of Et 2 O was added. After two days violet crystals were collected and washed with several portions of ether. sup-1

All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. Refinement. Refinement of F 2 against ALL reflections. The weighted R-factor wr and goodness of fit S are based on F 2, conventional R-factors R are based on F, with F set to zero for negative F 2. The threshold expression of F 2 > σ(f 2 ) is used only for calculating R- factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
