Tricarbonylchlorido(6',7'-dihydro-5'H-spiro[cyclopentane-1,6'-dipyrido[3,2-d:2',3'-f][1,3]diazepine]-[kappa]2N1,N11)rhenium(I)

Abstract top

In the title compound, [ReCl(C15H16N4)(CO)3], the ReI ion is coordinated in a distorted octahedral geometry by one Cl atom, two N atoms of the bidentate ligand and three carbonyl groups. The cyclopentane group is orientated in a transoid fashion with respect to the chloride ligand. The dihedral angle between the pryridine rings is 10.91 (12)°. In the crystal, N-H...Cl hydrogen bonds link complex molecules, forming a two-dimensional network parallel to (001).

Comment top

The title complex was prepared as part of a larger study into conjugation of [Re(3,3'-diamino-2,2'-bipyridine)(CO)3Cl] with oxo-steroids to form luminescent derivatives (Bullock et al. 2012). These steroids contain a cyclopentyl ring (ring D) with a ketone group in the 17-position; therefore, cyclopentanone was used as a model compound to examine the potential reactivity of such steroids with the rhenium complex. The photophysical properties of Re-polypyridyl complexes have been studied (Coleman et al., 2008) as well as the reaction of [Re(3,3'-diamino-2,2'-bipyridine)(CO)3Cl] with ketones (Clayton et al., 2008).

Single-crystal X-ray analysis of the product gave the structure shown in Fig. 1. The rhenium centre adopts a distorted octahedral coordination geometry and is coordinated by two nitrogen atoms from 3,3'-diamino-2,2'-bipyridyl and two carbonyl ligands in the equatorial positions (Re—N distances 2.158 (2) - 2.169 (2) Å, Re—C distances 1.924 (3) - 1.925 (3) Å). Carbonyl and chloride ligands occupy the axial positions (Re—C distance 1.891 (3) Å, Re—Cl distance 2.5046 (6) Å). The cyclopentyl ring is orientated in a trans-oid fashion with respect to the chloride ligand on the rhenium centre. In the crystal, N—H···O hydrogen bonds (see, Table 1) link complex molecules to form a two-dimensional network parallel (001).

A similar compound has been prepared using cyclohexanone instead of cyclopentanone. This compound is essentially isostructural with the compound reported here (Clegg et al. 2013).

Experimental top

To a solution of [Re(3,3'-diamino-2,2'-bipyridine)(CO)3Cl] in dichloromethane was added cyclopentanone (10 µL, ca 2 eq.) and a few grains of camphorsulfonic acid. The solution was stirred at room temperature for 2 h. The resulting precipitate was filtered in vacuo, washed with dichloromethane and dried, affording the product as a yellow solid. Slow evaporation of an acetonitrile solution of the complex gave yellow crystals suitable for X-ray analysis.

Refinement top

All non-hydrogen atoms were refined anisotropically. Hydrogen atoms on sp2 and sp3 carbons were placed in calculated positions (C—H = 0.95 - 0.99Å) and refined with riding constraints and with isotropic displacement parameters 1.2 x their parent carbon atoms. H atoms on the nitrogen atoms were treated similarly with N—H = 0.88Å.

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.
