A chain consisting of bridged rare earth clusters in compound (I). The cluster consists of an octahedron, the six vertices of which represent Yb atoms. H atoms and coordinated O atoms, except for sulfonate O atoms, have been omitted for clarity. [Symmetry codes: (i) −1 + x, y, z; (ii) 1 + x, y, z; (iii) 1 − x, 1 − y, 1 − z; (iv) 2 − x, 1 − y, 1 − z.] |
