(18-Crown-6-[kappa]6O)(pyrazolato-[kappa]2N,N')-potassium(I)

K. Kunz, H.-W. Lerner and M. Bolte

Abstract top

The asymmetric unit of the title compound, [K(C3H3N2)(C12H24O6)], is composed of a potassium cation bonded to the six O atoms of a crown ether molecule and the two N atoms of a pyrazolate anion. The K...O distances range from 2.8416 (8) to 3.0025 (8) Å, and the two K...N distances are 2.7441 (11) and 2.7654 (11) Å. The K cation is displaced by 0.8437 (4) Å from the best plane through the six O atoms. The latter plane is almost perpendicular to the plane of the pyrazolate ring [dihedral angle 83.93 (3)°].

Comment top

We report here the X-ray crystal structure analysis of the potassium pyrazolide as complex with 18-crown-6, [K(18-crown-6)(C3H3N2)] or [K(18-crown-6)(pz)]. Following the first synthesis of a scorpionate complex, considerable progress has been made towards extending this area of chemistry (Trofimenko, 1993). Our studies have shown that an important factor influencing the stability of scorpionates appears to be the degree of steric crowding around the boron centre. The results of investigations in our group show that the scorpionates RB(3–R'pz)3- and RB(4–R'pz)3- decompose in the presence of transition metal salts much more easily when R and R' are bulky (Bieller et al., 2006; Morawitz et al., 2008). Now we have found that irradiation of Mn(C5H3)(Bpz3)2(THF)2 (I) in the presence of 18-crown-6 leads to the formation of potassium pyrazolide (II).

The asymmetric unit of the title compound, [C12H24O6]K+[C3H3N2]-, is composed of a potassium cation bonded to the six O atoms of a crown ether molecule and the two N atoms of a pyrazolate anion. The K···O distances range from 2.8416 (8) Å to 3.0025 (8) Å, and the two K···N distances are 2.7441 (11) Å and 2.7654 (11) Å. The K cation is displaced by 0.8437 (4) Å from the best plane through the six O atoms. The latter plane is almost perpendicular to the plane of the pyrazolate ring [dihedral angle 83.93 (3) °].

Experimental top

Mn(C5H3)(Bpz3)2(THF)2 (64 mg, 75.4 µmol) was dissolved in THF (25 ml). The solution was irradiated using an UV lamp (TQ 150, λmax = 510 nm) for 16 h, whereupon the colourless solution turned orange. After stirring overnight at ambient temperature the reaction mixture was treated with 18-crown-6 (20 mg, 81.2 µmol) and was stirred for 10 minutes. After a small amount of colourless precipitate had been removed by filtration, the clear filtrate was evaporated to dryness in vacuo. Single crystals of (II) were grown from a solution of (II) in THF at -35°C.

Refinement top

H atoms were geometrically positioned and refined using a riding model with fixed individual displacement parameters [U(H) = 1.2 Ueq(C)] and with Caromatic—H = 0.95Å and Cmethylene—H = 0.99 Å.

Special details top

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.
