Compound (I) was prepared by the bridge-opening reaction of [{Rh(η4-C8H12)}2(µ-Cl)2] with (S)-2-methoxymethylpyrrolidine, similar to the procedure previously communicated for the syntheses of a number of chlorido(η4-1,5-cyclooctadiene)rhodium(I) derivatives bearing diverse N-bonded β-amino alcohol ligands (Dahlenburg et al., 2007). The specimen used for the X-ray diffraction study was collected from a partially evaporated NMR sample in CDCl3 solution.
Carbon-and nitrogen-bound H atoms were positioned geometrically (C—H = 0.95–0.99 Å; N—H = 0.93 Å) and refined using appropriate riding models. All hydrogen Uiso values were fixed at 1.2 times Ueq of the preceding carrier atom.
Chlorido(η4-1,5-cyclooctadiene)[κN-(S)-2-methoxymethylpyrrolidine]rhodium(I), [Rh(Cl)(η4-C8H12){(S)-C6H13NO}] (I), represents the O-methylated analogue of the previously described prolinol complexes [Rh(Cl)(η4-C8H12){(R)-C5H11NO}] and [Rh(Cl)(η4-C8H12){(S)-C5H11NO}] which themselves belong to a family of catalytically attractive rhodium compounds containing β-amino alcohol ligands (Dahlenburg et al., 2007). Complex (I) crystallizes from CDCl3 in the triclinic space group P1 with two independent moieties per cell.
Not unexpectedly, neither the Rh—Cl distances nor the Rh—N bond lengths deviate significantly from the corresponding dimensions observed fo closely related chlorido rhodium complexes in the literature possessing N-bonded ethanolamine, valinol, prolinol, and norephedrine ligands [Rh—Cl = 2.381 → 2.398 Å and Rh—N = 2.127→ 2.137 Å] (Dahlenburg et al., 2007).
In the solid state the individual complexes of (I) are assembled through N—H···Cl hydrogen bonds (Table 2). The (R)-enantiomer of the parent prolinol compound [Rh(Cl)(η4-C8H12)(C5H11NO)] shows similar N—H···Cl (and O—H···Cl) hydrogen-bonding between two crystallographically independent molecules (Dahlenburg et al., 2007).
For structurally related rhodium complexes with various chiral and achiral β-amino alcohol ligands, see Dahlenburg et al. (2007).

Chlorido(η4-1,5-cyclooctadiene)[κN-(S)-2-methoxymethylpyrrolidine]rhodium(I), [Rh(Cl)(η4-C8H12){(S)-C6H13NO}] (I), represents the O-methylated analogue of the previously described prolinol complexes [Rh(Cl)(η4-C8H12){(R)-C5H11NO}] and [Rh(Cl)(η4-C8H12){(S)-C5H11NO}] which themselves belong to a family of catalytically attractive rhodium compounds containing β-amino alcohol ligands (Dahlenburg et al., 2007). Complex (I) crystallizes from CDCl3 in the triclinic space group P1 with two independent moieties per cell.
Not unexpectedly, neither the Rh—Cl distances nor the Rh—N bond lengths deviate significantly from the corresponding dimensions observed fo closely related chlorido rhodium complexes in the literature possessing N-bonded ethanolamine, valinol, prolinol, and norephedrine ligands [Rh—Cl = 2.381 → 2.398 Å and Rh—N = 2.127→ 2.137 Å] (Dahlenburg et al., 2007).
In the solid state the individual complexes of (I) are assembled through N—H···Cl hydrogen bonds (Table 2). The (R)-enantiomer of the parent prolinol compound [Rh(Cl)(η4-C8H12)(C5H11NO)] shows similar N—H···Cl (and O—H···Cl) hydrogen-bonding between two crystallographically independent molecules (Dahlenburg et al., 2007).
