“…K 2 Nd 2 O(BO 3 ) 2 crystallizes in monoclinic P2 1 /c (No. 14) space group with unit cell parameters of a = 11.318(6) Å, b = 6.575(4) Å, c = 10.689(6) Å, β = 117.062(12)°, and Z = 4, which has an analogous structure to K 2 RE 2 O(BO 3 ) 2 (RE = La, Pr) [24,27] and Na 2 RE 2 O(BO 3 ) 2 (RE = Y, Nd, Gd, Er). [21,28,29] The K, Nd, B, and O atoms in an asymmetric unit of K 2 Nd 2 O(BO 3 ) 2 occupy two, two, two, and seven distinct Wyckoff sites, respectively.…”
