Geometry, Energy, and Some Electronic Properties of Carbon Polyprismanes: Ab Initio and Tight-Binding Study

Table 1

Bond lengths of various prismanes obtained within the NTBM model. Experimental values for prismane (cubane) are given in parentheses [19]. All bond lengths are quoted in angstroms.

Bond
	2	30	∞
	1.570 (1.571)	1.541 ÷ 1.561	1.541
	1.570 (1.571)	1.593 ÷ 1.642	1.641
	1.082 (1.097)	1.084	—
