The asymmetric unit of the title compound, (C8H20N)[Tc(C10H6NO2)Cl(CO)3], consists of two crystallographically independent technetium complexes related via a pseudo-inversion centre and two tetra­ethyl­ammonium cations. The Tc atoms have slightly distorted octa­hedral coordination geometries, and they are linked with the cations by inter­molecular C—H...O and C—H...Cl hydrogen-bonding contacts, forming two-dimensional columns, which lie approximately parallel to (001) in the crystal structure. The isochinolate (isoquinoline-1-carboxyl­ate) ligands link the columns by partial π–π stacking [centroid–centroid distance 4.3733 (11) Å], forming a three-dimensional network structure.

Comment top

The chemistry of technetium is well established for diagnostic purposes, where tricarbonyl Tc-99m and Tc-99m dicarbonyl-nitrosyl complexes are employed (Alberto et al., 1996; Rattat et al., 2001). The title compound, (I), is one of several synthesized using isochinolinic acid under a variety of ligands in order to study their coordination or complexation properties (Alberto et al. 1996). Clinical or biological test results are summarized in Waibel et al. (1999).

A careful check for missed symmetry in structures that crystallize in space group P1 with Z' = 2 is always good practice, as can be judged in two out of many critical articles: in his classic review, Marsh (1995) detected about 20 structures (described in space group P1 with Z = 4) which were shown to be better described by the monoclinic space groups No. 14 and 15; and some 60 space-group corrections have been reported (Marsh et al. 2002) of which four displayed the same missed symmetry. In (I), a pseudo-inversion centre (Fig. 1) and a pseudo-translation (Fig. 2) were found during the checking process using the programme PLATON (Spek 2003).

The independent Tc complexes are related by a non-crystallographic inversion centre located at (3/4, 3/4, 1/2) which is equivalent to a pseudotranslation t at (1/2, 1/2, 1) and is interpreted as a superstructure effect. The distribution of strong (h+k = 2n) and weak intensity reflections (h+k = 2n+1) in the (hk0) plane supports the view of a superlattice phenomenon (Fig. 2). Many homomolecular crystal structures were analysed with respect to non-crystallographic symmetry and superstructure effects, where only about 20 structures out of 1166 with Z = 4 showed local pseudo-centres of symmetry (Desiraju et al., 1991). The title compound belongs to a similar, heteromolecular class of structures with pseudoinversion centres, Z = 4 and with space group P1.

The pseudo-inversion related carbonyl atoms are found to point towards each other. The isochinolato ligands in both Tc complexes have bidentate coordination to the Tc atom via the aromatic amine N and carboxylate O atoms. This ligand, together with the two carbonyl ligands forms a distorted square planar environment around the Tc atom. The Cl atom and another carbonyl ligand are positioned trans to one another and complete the octahedral coordination geometry. The Tc coordination distances and angles are in comparable ranges, e. g. for Tc—CO (1.914 (7) - 1.927 (6) Å, Alberto et al. 1995) and 1.894 (3) - 1.912 (3) Å Alberto et al. 1996). Corresponding distances in the title complex vary between 1.905 (2) and 1.916 (2) Å, with an average value of 1.910 Å (Table 1).

The hydrogen bonding contacts in (I) can be described with the graph set descriptors D, C and R (Etter et al. 1990; Bernstein et al. 1995), with tetraethylammonium cations N1 and N2 as donor and the Tc complexes Tc1 and Tc2 as acceptor units. The tetraethylammonium donor group N1 is linked to acceptor atoms O31 (carbonyl), Cl1 and both carboxyl atoms O41, O51 of complex Tc1 to form weak intermolecular C—H···O and C—H···Cl hydrogen bonds (Desiraju & Steiner, 1999) with the graph set pattern D (Bernstein et al. 1995). Similar C—H···O and C—H···Cl hydrogen bond parameters (Table 2) were reported for tetrakis(pyridine) platinum(II) chloride trihydrate (Steiner & Saenger, 1993). The donor group of tetraethylammonium N2 is linked to both Tc complexes: Atom Cl1 is a bifurcated acceptor in complex Tc1, and the carboxylate group in complex Tc2 is an acceptor for the three-centre donor H19C in cation N2 (Table 2, Figure 3).

The hydrogen bonding contacts C151—H15A···O51 and C191—H19B···O41 represent a ring motif R22(8), whereas C171—H17A···O31 and C221—H22A···Cl1 are linked to form a chain motif C22(10). The contact C192—H19C···O52 can be seen as a simple motif D, or, together with the much weaker contact C192—H19C···O42 as a ring motif R21(4). The link C202—H20E···Cl1 may be considered as a very weak hydrogen bonding contact with motif D. The combination of the hydrogen bonding motifs form ladder-like columns with carbonyl and chloro units in the centre and isochinolato planes outside, the latter being able to form partial π···π stacking interactions between the independent rings C81 - C131 (Cg3) and N52, C42, C132, C82, C72, C62 (Cg6), with distances between centroids Cg3 and Cg6 = 4.3733 (11) Å, dihedral angle between ring planes = 6.83 °, and a slippage of 3.214 Å.

Experimental top

Caution! Tc-99 is a weak β-emitter with a half life of 2.12 × 105 years. Although radiation from low amounts of material is absorbed completely by the glass walls, reactions should only be carried out in specially equipped laboratories and under well ventilated hoods to avoid contamination or ingestion. Synthesis of the adduct [NEt4]2[TcCl3(CO)3] was prepared as described previously (Alberto et al. 1996). [NEt4]2[TcCl3(CO)3] was dissolved in methanol and 1 equivalent of isoquinolinic acid added to the solution. Stirring at room temperatur for about 4 h resulted in the quantitative formation of the title compound as observed from HPLC monitoring. The colour of the solvent turned to yellow. Methanol was evaporated and the residue taken up in THF. Slow evaporation of the THF gave yellow plates of (I) of good x-ray quality.

Refinement top

The missing cusp of data (alert level A in the PLATON checkcif) is due to data collection by rotation around the spindle axis only. This was standard at the time when the data were collected (in 1998) on a Stoe IPDS1 image-plate system.

All the hydrogen atoms were geometrically placed (C—H = 0.95-0.99 Å) and refined as riding with Uiso(H) = 1.2(Ueq(C) or 1.5Ueq(methyl C).

Special details top

Experimental. Due to the large crystal size a collimator of 0.80 mm diameter was used for the X-ray experiment.

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.
