Single crystals of LiCr(MoO 4 ) 2 , Li 3 Cr(MoO 4 ) 3 and Li 1.8 Cr 1.2 (MoO 4 ) 3 were grown by a flux method during the phase study of the Li 2 MoO 4 –Cr 2 (MoO 4 ) 3 system at 1023K. LiCr(MoO 4 ) 2 and Li 3 Cr(MoO 4 ) 3 single phases were synthesized by solid-state reactions. Li 3 Cr(MoO 4 ) 3 adopts the same structure type as Li 3 In(MoO 4 ) 3 despite the difference in ionic radii of Cr 3+ and In 3+ for octahedral coordination. Li 3 Cr(MoO 4 ) 3 is paramagnetic down to 7K and shows a weak ferromagnetic component below this temperature. LiCr(MoO 4 ) 2 is isostructural with LiAl(MoO 4 ) 2 and orders antiferromagnetically below 20K. The magnetic structure of LiCr(MoO 4 ) 2 was determined from low-temperature neutron diffraction and is based on the propagation vektor k⇒=(12,12,0). The ordered magnetic moments were refined to 2.3(1)μ B per Cr-ion with an easy axis close to the [111¯] direction. A magnetic moment of 4.37(3)μ B per Cr-ion was calculated from the Curie constant for the paramagnetic region.The crystal structures of the hitherto unknown Li 1.8 Cr 1.2 (MoO 4 ) 3 and LiCr(MoO 4 ) 2 are compared and reveal a high degree of similarity: In both structures MoO 4 -tetrahedra are isolated from each other and connected with CrO 6 and LiO 5 via corners. In both modifications there are Cr 2 O 10 fragments of edge-sharing CrO 6 -octahedra.
