摘要：
Single crystals of triclinic Pr-2(B2O5)(MoO4) were prepared from an incongruently melting flux in the system Pr2O3-MoO3-B2O3 in a platinum crucible in an atmosphere of air. In the crystal structure, distorted edge-sharing [PrO8] square antiprisms form a three-dimensional framework. These are further linked by isolated [MoO4] tetrahedra and isolated pyroborate groups [B2O5], the latter consisting of two independent trigonal [BO3] groups sharing one O atom. The [MoO4] tetrahedra and the [B2O5] groups are arranged in alternating layers parallel to the ab plane.
