Abstract	The layered oxyselenides with the formula LnCrSe2O (Ln = Ce Nd) were synthesized via molten salt methods. The isostructural compounds crystallize in the monoclinic space group of C2/m. The crystal structures feature 200[CrSe20]3 motifs stacked along the a axis, which are separated by Ln3 ions. The 2,0[CrSe20]3- layers are composed of [CrlSe6]9and [Cr2Se402]9- octahedra via corner and edge sharing. Powder X-ray diffraction results confirm the phase purities of the as-synthesized compounds. LnCrSe2O (Ln = Ce Nd) show typical antiferromagnetic ordering with TN = 125, 120, and 118 K, respectively. Heat capacity measurement for NdCrSe2O indicates that the Debye temperature is 278.4 K. Similar metal-to semiconductor phase transitions were observed for LnCrSe2O (Ln = Ce Nd) plates with transition temperatures of 115, 109, and 95 K, respectively. NdCrSe2O also possesses a magnetoresistance effect at low temperature (<25 K) with a significant positive magneto resistance,--, 16% at 2 K and 1 T.
