Tricaesium tris-(pyridine-2,6-dicarboxyl-ato-κO,N,O)lutetium(III) octa-hydrate.

Colourless block crystals of the title compound, Cs(3)[Lu(dipic)(3)]·8H(2)O [dipic is dipicolinate or pyridine-2,6-dicarboxyl-ate, C(7)H(3)NO(4)] were synthesized by slow evaporation of the solvent. The crystal structure of this Lu(III)-complex, isostructural with the Dy(III) and Eu(III) complexes, was determined from a crystal twinned by inversion and consists of discrete [Lu(dipic)(3)](3-) anions, Cs(+) cations and water mol-ecules involving hydrogen bonding. The Lu atom lies on a twofold rotation axis and is coordinated by six O atoms and three N atoms of three dipicolinate ligands. One Cs atom is also on a twofold axis. The unit cell can be regarded as successive layers along the crystallographic c-axis formed by [Lu(dipic)(3)](3-) anionic planes and [Cs(+), H(2)O] cationic planes. In the crystal structure, although the H atoms attached to water mol-ecules could not be located, short O-O contacts clearly indicate the occurrence of an intricate hydrogen-bonded network through contacts with other water mol-ecules, Cs cations or with the O atoms of the dipicolinate ligands.

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.
