(Received 25 November 2009; accepted 2 December 2009; online 4 December 2009)

The title complex, [Nd(C₁₅H₁₁O₂)(NO₃)₂(C₁₈H₁₅N₃O)]·CH₃CN or [Nd(altpy)(dbm)(NO₃)₂]·CH₃CN (altpy = 4′-allyloxy-2,2′:6′,2′′-terpyridine, dbm = dibenzoylmethanide anion), has been synthesized from 4′-allyloxy-2,2′:6′,2′′-terpyridine, dibenzoylmethanate and neodymium nitrate. The Nd³⁺ atom is nine-coordinated by two O atoms from the bidentate dbm ligand, three N atoms from the tridentate altpy ligand and four O atoms from two nitrate anions that act as bidentate ligands and occupy mutually trans sites in a distorted monocapped square-antiprismatic geometry.

Comment top

Lanthanide complexes are often used as shift reagents to probe metal-binding sites in solutions (Su et al., 1999) and they are also used in functional materials (Sutter et al., 1998) or catalysts (Aspinall et al., 1998). The ability of these elements to adopt coordination numbers from six to twelve provides a rich and variable structural chemistry. In the title compound, [Nd(altpy)(dbm)(NO₃)₂].CH₃CN(altpy=4'-allyloxy-2, 2':6', 2''-terpyridine, dbm=dibenzoylmethanate), each Nd(III) atom is in a nine coordinate environment comprising two oxygen atoms from the bidentate dbm ligand, three nitrogen atoms from the tridentate altpy ligand and four oxygen atoms from two tertiary nitrate anions that act as bidentate ligands an occupy mutually trans sites in the coordination polyhedron. The coordination polyhedron is a distorted monocapped square antiprism. The Nd—O distances lie in two groups, those to the beta-diketone oxygen atoms in the range 2.343 (2)–2.354 (2) Å and those to nitrate O atoms in the range 2.550 (3)–2.573 (3) Å. These are comparable to those [2.485 (19), 2.600 (15) Å] in the nine-coordinate complex [Nd₂(O₂CMe)₄(NO₃)₂(phen)₂] (phen=1,10-phenanthroline) which also contains bidentate chelating nitrate anions (Niu et al., 1997). The O—Nd—O angle (73.64 (8) °) of the beta-diketonate ligand is somewhat higher as compared to those found in the neodymium tris(beta-diketonates) type of complexes (Chen et al., 1998). The average Nd—N distance (2.595 (3) Å) is slightly longer than that in the nine-coordinate complex [Eu(terpy)(NO₃)₃^-(H₂O)] (2.554 Å)(Cotton et al. (2003)).The geometrical parameters of the [NO₃]^- anions in the title complex are as expected with normal distances and angles, comparable to those reported by Hunter et al., (2007) for a complex also containing bidentate chelating nitrate anions

Experimental top

The title compound was obtained by refluxing neodymium nitrate, 4'-allyloxy-2, 2':6',2''-terpyridine and dibenzoylmethanate in ethanol to give the title compound as a blue precipitate in 78% yield. Recrystallization from ethanol and acetonitrile (1:1) gave blue block-like crystals suitable for an X-ray diffraction determination. Anal.Calcd. for C₃₅H₃₀N₆NdO₉: C, 51.03, H, 3.64, N, 10.21%.

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.
