Tricarbonylchlorido(6′,7′-dihydro-5′H-spiro[cyclohexane-1,6′-dipyrido[3,2-d:2′,3′-f][1,3]diazepine]-κ²N¹,N¹¹)rhenium(I)

Abstract

In the title compound, [ReCl(C16H18N4)(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 cyclo­hexane group is orientated in a transoid fashion with respect to the chloride ligand. In the crystal, N—H⋯Cl hydrogen bonds link complex mol­ecules, forming a two-dimensional network parallel to (100).

Tricarbonylchlorido(6′,7′-dihydro-5′H-spiro[cyclopentane-1,6′-dipyrido[3,2-d:2′,3′-f][1,3]diazepine]-κ2N1,N11)rhenium(I)

“…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).…”

“…For the reaction of [Re(3,3 0 -diamino-2,2 0 -bipyridine)(CO) 3 Cl] with ketones, see: Clayton et al (2008). For the structure of the cyclohexane analog of the title compound, see: Clegg et al (2013).…”

A rhenium(I) complex which reacts with aldehydes and ketones in aqueous media: A structural, spectroscopic and theoretical analysis

“…The aldehyde has added across the 3,3′-diamino unit such that the benzaldehyde moiety lies in the equatorial plane of the bipyridine ring system. [17][18][19] Analysis of the isolated crystalline material by 1 H NMR shows double the amount of signals that would be expected for the complex 2d with one set of signals attributable to a minor component (~30%). Correspondingly, there are four possible isomers formed upon reaction with benzaldehyde ( Figure 2) with the phenyl unit reacting to give the equatorial or axial isomers ( Figure 2, i and ii).…”
