Figure 2
The environment of the potassium atom in KHBEt3, showing ten of the eleven K—H contacts < 3 Å to three neighbouring hydridotriethylborate units. Radii are arbitrary. K—H distances shorter than 2.8 Å are shown as thick dashed bonds, whereas those greater than 2.9 Å are shown as thin dashed bonds. The anion on the right corresponds to the asymmetric unit; the anions at top and bottom were generated by the operators + x, − y, 1 − z and − + x, − y, 1 − z, respectively. The contact to H2B of a fourth anion (at − x, 1 − y, − + z) is omitted for clarity. |
