Description

Red rod-shaped single crystals of Sm${}_7$F${}_{12}$Cl${}_2$ (CSD-2126941) with a length up to 0.3 mm were obtained after heating up a mixture of Sm, SmF${}_3$ and NaCl (as flux) in a sealed niobium capsule to 850 °C and cooling down the product with 5 °C/h after four days.
Sm${}_7$F${}_{12}$Cl${}_2$ crystallizes in the Ba${}_7$F${}_{12}$Cl${}_2$-type structure with a = 1004.52(7) pm, c = 394.75(3) pm and Z = 1 (space group: P-6) analogous to Eu${}_7$F${}_{12}$Cl${}_2$.
