Nd2SeSiO4 has been prepared as violet rod-like single crystals by reaction of elemental neodymium, selenium and iodine in the ratio 1.0:1.0:2.5 and subsequent reaction with quartz glass powder. The compound crystallizes in the orthorhombic space group Pbcm with a = 618.2(2), b = 717.4(2), c = 1102.4(2) pm and Z = 4. The structure is built up of alternating NdSe- and NdSiO4-sheets.
