Figure 1
(a) The asymmetric unit of (I), showing the numbering scheme for Cr and O atoms. For clarity, a ball-and-stick representation is used, and H atoms, solvent molecules, and labels for C atoms have been omitted. (b) The complete structure of (I), with displacement ellipsoids drawn at the 30% probability level, omitting solvent molecules, H atoms, and phenyl groups. (c) The {Cr8O4} core in (I), with displacement ellipsoids drawn at the 50% probability level. [Symmetry code: (i) −x + 2, y, −z + .] |
