Abstract
The present invention provides type-I and II carbon-based clathrate compounds stabilized by boron, including a boron-substituted, carbon-based framework with guest atoms encapsulated within the clathrate lattice. In one embodiment, the invention provides a carbon-based type-I clathrate compound of the formula Ca8BxC46-x.
Claims20
A carbon-based clathrate compound of the formula Ca8BxC46-x having a clathrate lattice structure.
A carbon-based clathrate compound of the formula M24BxC136-x having a clathrate lattice structure wherein M is a metallic element and wherein the clathrate lattice structure comprises sixteen small [512]-type (pentagonal dodecahedra) cages and eight large [51264]-type (hexadecahedra) cages.
A carbon-based clathrate compound having a clathrate lattice structure wherein the clathrate lattice structure includes carbon, boron, and at least one guest atom, wherein the clathrate lattice structure includes boron site occupation and the guest atom is chosen from a group of elements comprising sodium, strontium, and calcium.
