Synthesis and Crystal Structure of the Ternary Rare Earth Chlorides Na2MCl5 (M = Sm, Eu, Gd)Single crystals of Na2EuCl5 were obtained from the melt of NaCl and EuCl3 in a 2:1.2 molar ratio by slow cooling. It crystallizes in the orthorhombic crystal system (space group Pnma) with the structure of K2PrCl5 with a = 1 204.0(3) pm, b = 833.9(3) pm, c = 768.2(3) pm, Z = 4. Pure powder samples of the compounds Na2MCl5 (M = Sm—Gd) are available by heating mixtures of the binary components below the melting point.
Notes:
Einkristalle von Na2EuCl5 erhält man durch langsames Abkühlen einer Schmelze von EuCl3 und NaCl (molares Verhältnis 1,2:2). Na2EuCl5 kristallisiert orthorhombisch (Raumgruppe Pnma) im K2PrCl5-Typ mit a = 1 204,0(3) pm, b = 833,9(3) pm, c = 768,2(3) pm, Z = 4. Pulverproben der Verbindungen Na2MCl5 (M = Sm—Gd) gewinnt man durch Tempern von Gemengen der binären Komponenten.
