Materials Data on Ca21(Mn2Bi9)2 by Materials Project
Abstract
Ca21Mn4Bi18 is Magnesium tetraboride-derived structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are eleven inequivalent Ca sites. In the first Ca site, Ca is bonded in a 5-coordinate geometry to five Bi atoms. There are a spread of Ca–Bi bond distances ranging from 3.14–3.59 Å. In the second Ca site, Ca is bonded in a 6-coordinate geometry to six Bi atoms. There are a spread of Ca–Bi bond distances ranging from 3.15–3.43 Å. In the third Ca site, Ca is bonded in a 8-coordinate geometry to one Mn and seven Bi atoms. The Ca–Mn bond length is 3.39 Å. There are a spread of Ca–Bi bond distances ranging from 3.13–3.71 Å. In the fourth Ca site, Ca is bonded in a 6-coordinate geometry to six Bi atoms. There are a spread of Ca–Bi bond distances ranging from 3.15–3.52 Å. In the fifth Ca site, Ca is bonded in a 9-coordinate geometry to two Mn and seven Bi atoms. There are one shorter (3.46 Å) and one longer (3.47 Å) Ca–Mn bond lengths. There are a spread of Ca–Bi bond distances ranging from 3.26–3.71 Å. In the sixth Ca site, Ca is bonded in amore »
