text: Lu) have a unique crystal structure with two units – a cluster of B 12 icosahedra and a Si 8 ethane-like complex – and one bonding configuration (B 12 ) 3 ≡Si-C≡(B 12 ) 3 .
text: The icosahedra within one layer are linked through Si 8 ethane-like clusters with (B 12 ) 3 ≡Si-C≡(B 12 ) 3 bonds, as shown in figures 16a and b.
text: (b) bonding configuration (B 12 ) 3 ≡Si-C≡(B 12 ) 3 . .
text: Most parts of the crystal structure are the same as those described above; however, its bonding configuration is deduced as (B 12 ) 3 ≡C-C≡(B 12 ) 3 instead of (B 12 ) 3 ≡Si-C≡(B 12 ) 3 .
text: Existence of both bonding schemes of (B 12 ) 3 ≡Si-C≡(B 12 ) 3 and (B 12 ) 3 ≡C-C≡(B 12 ) 3 suggests the occpancy of the carbon sites of 50–100%.
