Abstract top

The title compound, [Ca3(C13H25N2O)6]·C6H14, is a trinuclear complex with all Ca atoms presenting octahedral coordination. The central Ca atom (as well as the hexane solvent molecule) is located on a crystallographic twofold rotation axis and is coordinated by six bridging O atoms, with Ca-O distances ranging from 2.344 (1) to 2.351 (1) Å. The terminal Ca atoms are coordinated by three bridging O atoms, with Ca-O distances ranging from 2.311 (1) to 2.335 (1) Å, and three N atoms of the [beta]-ketoiminate ligands, with Ca-N distances ranging from 2.432 (1) to 2.452 (1) Å. One of the diisopropylamino groups is disordered over two positions, with site occipancy factors of ca 0.54 and 0.46.

Comment top

The title compound was obtained by reaction between the Ca silylamide Ca[N(SiMe3)2]2(THF)2 (Westerhausen, 1991) and the ketoimine. Its solid state structure is similar to that of the strontium derivative. However, 1H NMR data in solution (CDCl3 or C6D6) show the presence of two different molecular species. In concentrated solution (1.4 M in CDCl3), one specie accounts for about 90% of the resonances while the amount of the second specie increases by dilution. These data suggest an equilibrium between a trinuclear form (I) having the solid state structure and a dimeric structure which could be similar to that reported for a tetrakis(β-ketoiminate)di-magnesium (Corazza et al., 1988).

In the title compound (I), the Ca atoms are hexacoordinated. The ketoiminate ligands are linked to the two terminal Ca atoms in a "three blades propeller" mode while the central Ca atom is bonded to the six bridging oxygen atoms of the six ligands and exhibits a distorded trigonal antiprismatic geometry. This coordination scheme is similar to that reported for the Sr analog (Pasko et al., 2005). An other very similar coordination scheme was also reported for a trimagnesium compound linked to a slightly different β-ketoiminate ligand (Matthews et al., 2005). For the terminal Ca atoms, the Ca—N distances [Ca1—N1 2.4323 (12), Ca1—N3 2.4522 (12) and Ca1—N5 2.4510 (12) Å] are in good agreement with those observed for the few β-ketoiminate known (Sanchez et al., 2002; Sarazin et al., 2006 & Westerhausen et al., 2003) while, due to the bridging nature of the O atoms, the Ca—O distances [Ca1—O1 2.335 (1), Ca1—O2 2.311 (1) and Ca1—O3 2.314 (1) Å] are longer than those reported. The Ca—O distances for the central Ca atom [Ca2—O1 2.344 (1), Ca2—O2 2.349 (1) & Ca2—O3 2.351 (1) Å] are in good agreement with those observed for bridging O atoms (see for example Deacon et al., 2004).

Experimental top

Synthesis of calcium 4-(2-diisopropylamino-ethylamino)-pent-3-en-2-onate [CaLiPr2]3. A solution of 885 mg (3.91 mmol) of 4-(2-diisopropylamino-ethylamino)-pent-3-en-2-one in 2 ml of hexane was added to 989 mg (1.96 mmol) of Ca[N(SiMe3)2]2(THF)2 in 10 ml of hexane. After stirring for 24 h at rt, concentration gave a white crystalline solid (648 mg, 68%). FT—IR (cm-1): 1618m (νC=O); 1589m, 1578 s, 1517m (νC=C); 498 s (νCa=N). 1H NMR (250 MHz, CDCl3); 1.01 [d, 72H, Me(iPr), 3 J = 6.65 Hz); 1.92, 1.99 [s, 36H, Me(acac)]; 2.59 (t, 12H, CH2—NiPr2, 3 J = 7.43 Hz); 3.00 [sep, 12H, CH(iPr)), 3 J = 6.71 Hz]; 3.2 [t, 12H, CH2—N(acac)]; 4.94 [s, 6H, CH(acac)] for B; 0.90 [d, 72H, Me(iPr), 3 J = 6.47 Hz); 1.73, 1.85 [s, 36H, Me(acac)]; 2.33 (t, 12H, CH2—NiPr2, 3 J = 5.84 Hz); 2.88 [sep, 12H, CH(iPr), 3 J = 6.64 Hz]; 3.22 [t, 12H, CH2—N(acac)]; 4.54 [s, 6H, CH(acac)] for (I).

Refinement top

The complex as well as the solvate molecule are located on a twofold axis and only the half of these molecules are present in the asymetric unit. One of the di(isopropyl)-amino groups was found to be disordered over two positions [occupancies: 0.537:0.463]. The lenghts of equivalent bonds in both components of the disordered groups were restrained to be similar during refinement. All H atoms were placed in idealized positions (C—H=0.93 to 0.98 Å) and refined using a riding model [Uiso(H)=1.2Ueq(CH, CH2) and 1.5Ueq(CH3)]. Torsion angles of the methyl groups attached to sp2 C were refined.

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.
