The compound described by Np2O3 is Corundum structured and crystallizes in the trigonal R-3c space group. Np(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted edge, face, and corner-sharing NpO6 pentagonal pyramids. O(1) is bonded to four equivalent Np(1) atoms to form a mixture of distorted edge and corner-sharing ONp4 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
