## Abstract The new title compounds are prepared from the elements by induction melting (Ar, 1370 K, 30 min) followed by annealing at 670 K for 4 weeks.
The title compounds are prepared by hydrothermal reaction of K2CO3 and LnF3 at 740 • C and 220 MPa. The isostructural compounds crystallize in the rhombohedral space group R32 with Z = 3. The structure consists of KLn2(CO3)3 carbonate and K3F4 fluoride sheets. K4Eu2(CO3)3F4 exhibits a frequency doub
The compounds Ba4Nd2Cd3Se10 and Ba4Ln2Cd3S10 (Ln ؍ Sm, Gd, Tb) have been synthesized at 1173 K with the use of a BaBr2/ KBr eutectic 6ux. These isostructural compounds crystallize as racemic twins in space group Cmc21 of the orthorhombic system in cells of (Ln, Q, a, b, c (A s ), T (K)
