Single crystals of NdBO2MoO4 were obtained from a molybdenum oxide–boron oxide flux under an air atmosphere. The structure features double chains of edge- and face-sharing distorted [NdO10] bicapped square-antiprisms, which are linked by rows of isolated [MoO4] tetrahedra and by zigzag chains of corner-sharing [BO3] groups, all of them running along the b axis. The chains of [NdO10], chains of [BO3] and rows of [MoO4] groups are arranged in layers parallel to the bc plane.
A rough investigation of subsolidus phase relations in the pseudo-ternary system Nd2O3 – B2O3 – MoO3 has been reported by Lysanova et al. (1983 ▶) and Dzhurinskii & Lysanova (1998 ▶). X-ray powder diffraction data of LnBO2MoO4 (Ln = La, Ce, Pr, Nd) are given by Lysanova et al. (1983 ▶). The occurrence of a structural phase transition of LaBO2MoO4 was reported by Becker et al. (2008 ▶). For determinations of related structures, see: Palkina et al. (1979 ▶); Zhao et al. (2008 ▶, 2009 ▶) for LaBO2MoO4; Zhao et al. (2008 ▶) for CeBO2MoO4.
