✦ Synopsis

The structure of (\mathrm{Nd}{3} \mathrm{BGe}{1.08} \mathrm{Si}{0.92} \mathrm{O}{10}) has been determined by a single crystal investigation. The orthorhombic cell parameters are (a=9.845(1) \AA, b=7.146(1) \AA), and (c=23.382(2) \AA). The space group is (P b c a(Z=8)). Out of 10,833 measured reflections, 3,099 independent reflections ((I>3 \sigma(I))) have been used in the refinement of the structure. The (R) factor value is (0.026(w R=0.023)). The neodymium ions occupy three different sites with eight or nine oxygen bonds in the lattice. The germanium and silicon ions are located in a distorted tetrahedral environment. The boron atom coordination is triangular with a shorter (B-O) distance of (1.384 \AA \AA . \quad 01994) Academic Press, Inc.
