摘要：

The molecular and crystal structures of the boron nitride E-phase are determined. Analysis of all calculated for the first time main peaks of Xray diffraction patterns (6.28, 3.85, 3.28, 2.72, 2.50, 2.22, 2.09, 1.92 angstrom) in comparison with experimental ones indicates that E-BN has the 07) diamond-type lattice (the cell constant a= 10.877 angstrom, the space group Fd3m or h formed with T-h, symmetry B12N12 molecules copolymerized by the hexagonal faces. Hence we propose to mean "extradiamond" term instead of "explosion" term in the E-phase name. Extradiamond-B12N12 has a framework type of faujasite and can be referred to as [B12N12]-FAU zeolite. Ideal crystal of E-BN has 192 atoms perunit cell and theoretical density of 3.074 g/cm(3). (c) 2005 Elsevier B.V. All rights reserved.
