The tetra(tert-butyl)-tetraazido-borazocine, 1, has the expected tub shape as determined for (SCNB=NtBu)4. However, it crystallizes in the triclinic system and shows no symmetry element in contrast to the isothiocyanato derivate which has C2 symmetry. There are two kinds of BN bonds which alter from long to short (average 1.491 and 1.388 Å). The BN bond lengths to the azido groups are, on avera...

The borazocine (ClB=NCMe3)4 crystallizes in the monoclinic system, space groupC2/c with Z = 6, i. e. there are two independent molecules in the unit cell. The first molecule has no crystallographic symmetry, while the second molecule is characterized by a twofold axis which generates the (ClB= NCMe3)4 molecule from the fragment (ClB=NCMe3)2. The molecules are tub-shaped showing alternating long...
