| Figure 1 (a) Schematic representation of the binuclear centrosymmetric anionic [Ho2(NDC)6(H2O)6]6− unit showing the labelling scheme for all non-H atoms composing the asymmetric unit. Displacement ellipsoids are drawn at the 80% probability level and H atoms are represented as small spheres with arbitrary radii. (b) Magnification of the {Ho2O2(CO2)4(H2O)6} core of the binuclear unit, emphasising the highly distorted {HoO8} dodecahedral coordination environment for the Ho3+ centres. For selected bond lengths and angles of the {HoO8} coordination polyhedron see the Table summarising the geometrical details. Symmetry codes used to generate equivalent atoms: (i) 2-x, -y, 1-z; (ii) 1 + x, y, -1 + z. |
