摘要: One of the most interesting properties boron is its ability to combine with itself form polyhedral structures. Of various forms, those in which atoms occupy twelve vertices an icosahedron or cubo-octahedron are common, although octahedral unit consisting six at well known and characteristic hexaborides tetraborides. This review concerned establishing structural determinants common borides modifications contain B12 units. In addition, case tetraborides considered some detail, since it this system that units cease act as determinant.
