The 2D layered structure of MXene has hexagonal space group (P63/mmc, No. 194) symmetry, with generic chemical formula of Mn+1Xn, or Mn+1XnT in presence of surface passivation where T denotes the surface termination by H, OH, or F, which may happen during the experimental acid etching...
P Villars,K Cenzual 摘要: Volume 43 of Group III deals with crystallographic data of both intermetallic and classical inorganic compounds, thus forming an update of the former Landolt-Börnstein volumes III/6 (Structure Data of Elements and Intermetallic Phases) and III/7 (Crystal Structure ...
if G is a p-group of order p(m) and exponent p,m > 3,n is-an-element-of {2,...,m-2), then [1] G contains 1+p+2p2+kp3 (k greater-than-or-equal-to 0 is an integer) subgroups of order p(n). In this note we prove an analogous result for irregular p-groups, p > ...

There are 39 CRYSTMETentries in the hexagonal space group P-3m1 (164) reporting both distinct pure phase compounds and atomic coordinates. Having the same Wyckoff positions in the same space group as the C6 structure type, all are isopointal with it. The range of observedc/avalues extends ...
