Dicarbon­yl[2-hydr­oxy-3,5,7-tris­(mor­pho­linomethyl)cyclo­hepta-2,4,6-trien­onato(1–)-κ2O1,O2]rhodium(I)

Abstract

In the title compound, [Rh(C22H32N3O5)(CO)2], the RhI atom is coordinated by two carbonyl ligands and two tropolonate O atoms in a distorted square-planar geometry. It is an example of a new type of tropolone derivative that has not been characterized via solid-state methods. Weak intra­molecular C—H(...)N and inter­molecular C—H(...)O hydrogen bonds, and π–π stacking inter­actions between the tropolone rings [centroid–centroid distance = 3.590 (8) Å] are observed in the crystal structure.

Comment

Tropolone type compounds have been of interest since its first discovery in the early 1940's (Dewar, 1945), with applications in pharmacology (Banwell et al., 1992; Kierst et al., 1982) and catalysis (Burgstein et al., 1998; Crous et al., 2005). A recent report on the anti-viral activity of morpholine derivatives of tropolone (Doering Knox) indicated moderate to strong activity against the hepatitis C virus strain (Boguszewska-Chachulska et al., 2006). The addition of morpholine groups to a compound increases its water solubilty properties and thus simplifying the method of dosage, i.e., pallative. Although this compound has been extensively studied, the preferred orientation of the morpholine groups are unknown, as well as the geometrical properties of the tropolone ring system. In this regard, we present a dicarbonyl rhodium(I) complex of a 3,5,7-tris(methylmorpholine)tropolonate ligand (Fig. 1; Table 1).

The molecular packing of the title compound is strongly influenced by the morpholine moieties as these form extensive hydrogen bonding networks (Table 2). A close Rh1···Rh1i contact [3.2826 (3)Å; symmetry code: (i) 1-x, y, 0.5-z] exists between associated metal centres. This short contact is stabilized by π–π stacking between the corresponding cycloheptatriene rings, with a centroid–centroid distance of 3.590 (8)Å and an interplanar angle of 3.99 (5)°. The slight twist of the two cycloheptatriene ring systems can be attributed to the methylmorpholine functional groups creating a sterically crowded environment.

The crystal packing of diketonate dicarbonyl rhodium(I) complexes tends to favour a head-to-tail packing mode. The [Rh(tropolonate)(CO)2] complex (Steyl et al., 2004) was deemed to be a singular occurance of the head-to-head packing mode of these molecular systems. The title compound exhibits a slightly distorted orientation as defined by the O1—Rh1—Rh1i—O2i torsion angle of 37.09 (3)°. This observation is surprising since the addition of bulky groups on the 3,7-positions was expected to force the molecular system in the head-to-tail packing mode. The π–π stacking and hydrogen bonding interactions stabilize the crystal structure.

Experimental

The title compound was synthesized by the addition of 3,5,7-tris(methylmorpholine)tropolone (0.083 g, 0.32 mmol) to an acetone solution of [Rh(µ-Cl)(CO)2]2 (0.100 g, 0.29 mmol). On slow evaporation of the solvent, crystals suitable for X-ray analysis was obtained (yield 30%, 0.045 g).

Refinement

H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.95 (CH) and 0.99 (CH2) Å and Uiso(H) = 1.2Ueq(C).
