The crystal structure is shown in the figure. Tables 13 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters.

Source of material

fac-[NEt4]2[Re(CO)3Br3] (500 mg; 0.649 mmol) was dissolved in water (10 ml) at pH 2.2 and AgNO3 (331 mg; 1.947 mmol) was added. The solution was stirred overnight for 16 hours at room temperature and the precipitated AgBr was filtered off and weighed (367 mg; 1.955 mmol). Hexafluoroacetylacetone (0.135 g; 0.649 mmol) was added to the solution and stirred for 24 hours at room temperature. The orange precipitate, fac-[NEt4]2[Re(Hfaa)(CO)3NO3], was filtered off, washed, dried and weighed. (Yield: 274 mg; 86%). Crystals of the title complex was obtained from crystallization of the precipitate in MeOH. Yield = 148 mg; 40%. IR (KBr, cm−1): νCO (2023, 1880).

Experimental details

In the structure all the H atoms were positioned geometrically and refined discernible using a riding model, with C—Hmethine = 0.98 Å; C—Hmethyl = 0.96 Å; C—Haromatic = 0.93 Å. The H atom isotropic displacement parameters were fixed; Uiso(H) = 1.2Ueq(C) for aromatic and methine and Uiso(H) = 1.5Ueq(C) for methyl protons, allowing them to ride on the parent atom. The CF3 substituents on the beta-diketone backbone are both structurally disordered, as manifested by the fluoro-atoms on both carbons (C4 and C8), occupying six positions on each carbon with occupancies of 0.181(16) (for F4A, F5A and F6A) and 0.819(16) (for F4B, F5B and F6B) on C4, and 0.724(13) (for F1A, F2A and F3A) and 0.276(13) (for F1B, F2B and F3B) on C8 [1]. In one case, F1A, F2A and F3A displays the dominant occupancy, and in the other case, F4B, F5B and F6B.

Discussion

Researchers are continually showing interest in the fac-[M(CO)3]+ [M = Re, Tc] synthon, particularly the fac-[Re(CO)3(OH2)3]+ moiety, primarily because of its potential use in the design of new diagnostic and therapeutic radiopharmaceuticals [2–4]. A considerable amount of work, involving the rhenium tricarbonyl core has already been published from our group, and this study forms part of on-going research, aimed at studying the chelation behaviour and structure and reactivity of the rhenium(I) metal centre and other middle and late transition metal complexes' behaviour when coordinated to β-diketone types of ligands [5–15].

The title compound, fac-[NEt4][Re(CO)3(Hfaa)(NO3)], consists of three facial coordinated carbonyl ligands, a fluorinated β-diketone ligand (hexafluoroacetylacetonate-Hfaa) in the axial position, a nitrate ligand in the equatorial plane, as well as a counterion, tetraethylammonium (NEt4), in the asymetric unit (see the figure, upper part). The coordination at Re(I) is a distorted octahedron, as seen in the C3—Re1—O6 (170.30(19)°) angle which deviates from 180°. The O4—Re1—O5 bite angle of 84.14(15)° correlates well with a similar hexafluoroacetylacetonate coordinated Re(I) complex, 84.56(8)° [6]. The bond distances in the coordination polyhedron, are within normal range when compared to a similar structure, ranging from 1.892(6) to 2.157(4) Å [16]. The molecules within the unit cell are packed in horizontal layers, in a head-to-head manner, when viewed along the c-axis. These layers are stabilised by intermolecular C—H⋯O bonds (see the figure, lower part).
