NaOH (2 mmol, 0.08 g) in methanol (10 ml) was added in five portions to a boiling solution of Nd(ClO4)3.nH2O (8 mmol, 1.346 g N d2O3) in methanol (10 ml). A solution of 2,6-diformyl-4-methylphenol (4 mmol, 0.6566 g) and NaOH (4 mmol, 0.16 g) in methanol (150 ml) was then added to the boiling solution in 20 ml portions. After each addition of sodium cresolate, the mixture was boiled until approximately 10 ml of solution remained before adding the next 20 ml portion. The pH of the mixture at this point was approximately 6.5. The final mixture was boiled until 5 ml of solution remained. It was then cooled and filtered and approximately 10 ml of ethanol was added. The resulting mixture was left in an open flask at room temperature. The onset of crystallization was obvious after 3 d but a further 2 d were allowed for the process to proceed to completion. Yellow blocks of (I) were recovered in 20% yield (calculation based on LnIII). The crystals lost solvent and crumbled to an amorphous solid on exposure to air. CAUTION: Although no problems were encountered in this work, perchlorate compounds are potentially explosive. They should be prepared in small amounts and handled with care.
One of the percholate anions (Cl2/O18/O19/O20/O21) is disordered over two sites, with an occupancy ratio of 0.577 (4)/0.423 (4) for the major and minor components. Both components of disorder have the site of O18 in common. In addition, one of the µ2-C9H7O3 ligands (containing the benzene ring C11/C11A/C12/C13/C13A/C14) is also disordered; initial refinement gave equal values within experimental error for the two disorder components; the occupancy ratio was therefore fixed at 0.5:0.5 in the final cycles. This disordered ligand is bisected by the crystallographic twofold axis but the disorder is not imposed by the crystallographic symmetry. All H atoms bonded to C atoms were placed in calculated positions, with C—H distances of 0.95 or 0.98 Å (methyl), and were included in the refinement in the riding-model approximation, with Uiso(H) = 1.2Ueq(C), or 1.5Ueq(C) for methyl H atoms. The H atoms of the bridging hydroxyl ligands were included with O—H = 1.00 Å and Uiso(H) = 1.2Ueq(O). All other H atoms bonded to O atoms were placed in calculated positions based on an ideal location for O—H···O hydrogen bonding. The O—H distance was fixed at 0.84 Å with Uiso(H) = 1.5Ueq(O). During the refinement, areas of electron density were located in difference Fourier maps that were assigned as ethanol solvent molecules. The peak pattern of electron density suggested that the solvent molecules were highly disordered, and attempts to model the disorder were unsuccessful. In the final cycles of refinement, the contribution to electron density corresesponding to the disordered ethanol molecules was removed from the observed data using the SQUEEZE option in PLATON (Spek, 2003). The resulting data vastly improved the precision of the geometric parameters of the remaining structure. The contributions of two molecules of ethanol have been included in the molecular formula. The hydroxy groups of the ethanol molecules, if present, would contribute to the hydrogen-bonding motif, and for that reason the hydrogen bonding in the title structure is not discussed in detail. In the final difference Fourier map, the three largest density peaks in the range 1.64–1.06 e Å3 were located within 1.23 Å of the disordered perchlorate anion, and the deepest hole of −1.16 e Å3 was 0.80 Å from Nd1.

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. |

There is currently tremendous interest in the synthesis and characterization of finite polylanthanide(III) entities with nanoscopic dimensions (Zheng, 2001; Wang et al., 2002). This interest lies in several application fields, since lanthanide clusters are potential precurors for ceramics, catalysts and thin-film coatings (Hubert-Pfalzgraf, 1995). Nanoclusters with mutually interacting LnIII ions are also expected to yield new materials with greater versatility resulting from unusual enhancements in magnetic, catalytic, optical and electronic properties (Thompson et al., 2003, 2001). The title compound, (I), is one of a series of similar LnIII compounds synthesized in an investigation into the formation chemistry of nanoclusters which feature commonly encountered aggregation motifs such as [Ln4(OH)4]8+. We have previously determined the structure of the cation in the title structure as the trifluoromethanesulfonate (Singh-Wilmot et al., 2005).
The cation in (I) features four NdIII and four µ3-hydroxo groups occupying alternate vertices of a distorted cube (Fig. 1). Selected bond distances are given in Table 1. Each NdIII ion is in a ninefold coordination polyhedron of an approximate tricapped trigonal prism and approximate D3 h symmetry, with a shortest metal–metal contact of Nd2···Nd2i = 3.7003 (4) Å [symmetry code: (i) −x, y, 1/2 − z]. This distance is comparable with metal–metal distances seen in other complexes containing a similar cubane-type [Ln4(µ3-OH)4]8+ core, for example ca 3.83 Å for the shortest Sm···Sm distance in [Sm4(µ3-OH)4(Gly)5(H2O)11]) (Evans et al., 2000). Nd—O(phenolate) distances are in the range 2.546 (3)–2.597 (3) Å, while the Nd—O(carbonyl) distances are in the range 2.441 (4)–2.484 (4) Å. The range of Nd—O(µ3-OH) distances [2.393 (3)–2.472 (3) Å] compares well with those in [Nd4(µ3-OH)4(Ala)6(H2O)10] (ca 2.43 Å; Zheng & Wang, 2000).
