(2,2′-Bipyridyl)bis[N,N-bis(2-hydroxyethyl)dithiocarbamato-κ²S,S′]cadmium(II)

The title compound, [Cd(C₅H₁₀NO₂S₂)₂(C₁₀H₈N₂)], features a trigonal-prismatic coordination geometry for the Cd^II ion, based on an N₂S₄ donor set defined by two chelating dithiocarbamate ligands and a 2,2′-bipyridyl ligand. In the crystal, extensive O—H

O hydrogen bonding results in the formation of 12-membered {

HO}₆ synthons and one-dimensional supramolecular chains with further O—H

S interactions providing additional stability to the linear chain with base vector [01 $\overline{1}$ ].

Comment top

Interest in the title compound, (I), relates to crystal engineering endeavours with the zinc-triad 1,1-thiolates (Lai et al., 2002; Tiekink, 2003; Chen et al., 2006), in particular with functionalized dithiocarbamate ligands (Benson et al., 2007). The cadmium atom in (I), Fig. 1, is chelated by two dithiocarbamate ligands that form asymmetric Cd–S bond distances (Cd–S1, S2 = 2.6021 (14) and 2.7586 (13) Å; and Cd–S3, S4 = 2.6310 (15) and 2.7258 (15) Å) and by the 2,2'-bipyridyl ligand (Cd–N3, N4 = 2.395 (4) and 2.361 (4) Å). The resulting N₂S₄ donor set defines a trigonal prismatic geometry.

The prominent feature of the crystal structure is the formation of a supramolecular chain with base vector [0 1 1]. These form as a result of 12-membered {···OH}₆ synthons involving the O2-, O3-, and O4-hydroxyl groups; the O1-hydroxyl group forms a hydrogen bond to the S3 atom, Table 1 and Fig. 2. The 12-membered synthons have a flattened chair conformation.

Experimental top

Compound (I) was prepared following the standard literature procedure from the reaction of Cd[S₂CN(CH₂CH₂OH)₂] and 2,2'-bipyridyl (Lai & Tiekink, 2004). Colourless crystals were obtained from the slow evaporation of a chloroform/ethanol solution of (I).

Special details top

Geometry. 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 F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
