In the title compound, [Na(ClO4)(C24H20N6)], the sodium cation is in a square-pyramidal geometry, which is distorted from the ideal (τ = 0.19), with the four N-donor atoms of the bis-bidentate chelating units from the ligand arranged equatorially, and with the perchlorate anion at the apical site.

Comment top

The coordination chemistry of the ligand L1 has been well documented for the first row transition metals; it forms tetrahedral cages and open-chain dinuclear structures (Fleming et al., 1998; Paul et al., 2002). Several complexes of alkali metals with N-donor ligands are observed in the literature, although they usually employ highly preorganized ligands, where the cavity size is comparable to that of the alkali metal ion and the coordination geometry is particularly unsuited to a transition metal. Examples include ligands such as torands (Bell et al., 1992; Bell et al., 1993), macrocycles (Constable et al., 1988) and cryptands (Lehn & DeVains, 1992). However, a helical structure containing K+ ions has been reported, based on a hexadentate N-donor ligand which consists of two terdentate binding domains (Psillakis et al., 1997).

The molecular structure of the title compound is shown in Fig. 1. It is a relatively unusual example of an alkali metal complex with an open-chain N-donor chelating ligand. The sodium cation is surrounded by four nitrogen donors from L1 and a single perchlorate anion, thus yielding a neutral complex. The Na—N average bond length is 2.487 Å, which is comparable to the Na—N average bond length found in six-coordinate chelate complexes with the bidentate phen unit (Qian et al., 1994). Although there are many sodium complexes reported with cryptands (Echegoyen et al., 1991; McKee et al., 1992), the comparison of bond lengths can be complex, since it is thought that they are, in part, dependent on the rigidity of the ligand and the coordination number of the Na+ ion (Caron et al., 1985). The N atoms of the ligand unit are not bound to the sodium ion in a plane. One of the pyrazole–pyridine units is approximately planar, but the other has an angle of 17.1 (2)° between the rings. The approximate angle between the bidentate arms is 131.9 (14)°, thus enabling the perchlorate anion to coordinate comfortably to the Na+ ion in the apical position. The Na—O bond length is 2.3359 (18) Å.

For a five-coordinate geometry, there is a structural continuum between the ideal square-pyramidal (SP) and trigonal-bipyramidal (TBP) extremes. The structural index parameter τ (degree of trigonality) can be defined as τ = (β-α)/60, where β and α are the largest and smallest angles, respectively, at the central atom. τ is equal to zero for a perfect SP geometry, and equal to unity for a perfect TBP geometry (Addison et al., 1984). For the title compound, τ = 0.19, indicating that the coordination geometry of sodium is closer to, but distorted from, ideal square pyramidal.

Experimental top

Crystals of the title compound were obtained via a serendipitous route upon reaction of (CH3CO2)3Mn·2H2O and L1 in a 2:3 ratio in methanol. An aqueous solution of NaClO4 was added, to afford a white precipitate, which was collected by filtration. The title compound was isolated upon recrystallization of the precipitate from MeCN/Et2O.

Refinement top

All H atoms were constrained to ideal geometries, with C—H distances of 0.93 and 0.97 Å, and assigned isotropic displacement parameters 1.2Ueq of their parent C atoms.

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.
