Most of the title compounds were prepared by reaction of the rare-earth metaperrhenates Ln(ReO 4 ) 3 with the rare-earth metals in sealed silica tubes. Nd 4 Re 6 O 19 was obtained by reaction of the intermetallic compound NdRe 2 with the metaperrhenate Nd(ReO 4 ) 3 . The compounds Ln 2 ReO 5 crystal
The title compounds are prepared by hydrothermal reaction of K2CO3 and LnF3 at 740 β’ 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
