Description / Table of Contents:
Divalent Neodymium: NdCl2 and KNd2Cl5Single crystals of NdCl2 have been obtained via metallothermic reduction of NdCl3 with lithium: a = 908.49(5), b = 761.47(5), c = 455.62(2) pm, Pbnm, Z = 4, PbCl2 type, refined to R = 0.047. Reduction of NdCl3 with potassium yields KNd2Cl5: a = 894.51(9), b = 785.16(7), c = 1 265.28(13) pm, β = 90.000(8)°, P21/c, Z = 4, isotypic with TlPb2Cl5. There is a close structural relationship of KNd2Cl5 with K2NdCl5.
Notes:
Bei der „metallothermischen Reduktion“ von NdCl3 mit Lithium werden Einkristalle von NdCl2 erhalten: a = 908,49(5); b = 761,47(5); c = 455,62(2) pm; Pbnm, Z = 4, PbCl2-Typ, Verfeinerung bis R = 0,047. Kalium reduziert NdCl3 unter Bildung von KNd2Cl5: a = 894,51(9); b = 785,16(7); c = 1265,28(13) pm; β = 90,000(8)°, P21/c, Z = 4, isotyp mit TlPb2Cl5. Es besteht eine enge strukturelle Verwandtschaft mit K2NdCl5.
