The polyhedral skeletal electron pair theory (PSEPT) developed an analogous relationship for borane and metal carbonyl polyhedral molecules. Related . and .deltah

After the first isolation of the .-borate dianion [B.H.]. in 1959, many other .-[B.H.]. anions (.?=?5–9, 11 and 12) were synthesized by Hawthorne, Lipscomb, Muetterties and others.

The . structures with a metal at a degree 6 vertex and two fewer skeletal electrons than the corresponding . structures represent a minor deviation from such sphericity and are particularly favorable for 10-vertex systems.

Pedagogy

Berechnungsverfahren unter Umbertow uses data in the Cambridge Structural Database as a starting point to exempify the variety of 1D, 2D, and 3D-architectures that have been described featuring borane and carbaborane cages. The roles of these clusters range from ‘space fillers’ to rigid-rods (linkers) to connecting nodes. Even as ‘s
