A small amount of silicon addition to ScB19 which decomposes at elevated temperatures without melting allowed it to coexist with the liquid phase and as a resultant made the floating zone crystal growth possible. Powder X-ray diffraction analysis confirmed the grown crystals of ScB19+xSiy to be isostructural to ScB19. It was found that the crystal structure of ScB19+xSiy solved based on single-crystal X-ray data is tetragonal with lattice constants of a, b=1.03081(2) nm, c=1.42589(3) nm, space group P41212 or P43212 and is basically isotypic with α-AlB12 structure type. In the crystal structure boron atoms form a three-dimensional framework based on interconnected B12 icosahedra and B22 polyhedra. The Sc atoms reside in three of five Al sites in the α-AlB12 structure and Si resides in a bridge site bonding two B22 units.

Single crystals were obtained by the floating zone method by adding a small amount of Si. Single-crystal structure analysis revealed that the compound has an orthorhombic structure with lattice constants of a=1.73040(6), b=1.60738(6) and c=1.44829(6) nm and space group Pbam (No. 55). The crystal composition ScB13.3C0.78Si0.008 calculated from the structure analysis agreed with the measured composition of ScB12.9C0.72Si0.004. The orthorhombic crystal structure is a new structure type of boron-rich borides and there are six structurally independent B12 icosahedra I1—I6, one B8/B9 polyhedron and nine bridging sites all which interconnect each other to form a three-dimensional boron framework. The main structural feature of the boron framework structure can be understood as a layer structure where two kinds of boron icosahedron network layer L1 and L2 stack each other along the c-axis. There are seven structurally independent Sc sites in the open spaces between the boron icosahedron network layers.

The observed crystal defects and deformations were correlated with changes in the crystal growth process. The interplay beween systematic characterization and process improvements results in the growth of high quality single crystals of YB66 that can be used as an efficient element for monochromatization of synchrotron soft X-ray in the 1 2 keV energy range.

Single crystallites were obtained as an intergrowth phase in the float-zoned single crystal of Sc0.83−xB10.0−yC0.17+ySi0.083−z that has a face-centered cubic crystal structure. Single crystal structure analysis revealed that the compound has a hexagonal structure with lattice constants a = b = 1.43055(8) nm and c = 2.37477(13) nm and space group P-6m2 (No. 187). The crystal composition calculated from the structure analysis for the crystal with x = 0.52, y = 1.42, z = 1.17, and w = 0.02 was ScB12.3C0.58Si0.10 and that agreed rather well with the composition of ScB11.5C0.61Si0.04 measured by EPMA. In the crystal structure that is a new structure type of boron-rich borides, there are 79 structurally independent atomic sites, 69 boron and/or carbon sites, two silicon sites and eight scandium sites. Boron and carbon form seven structurally independent B12 icosahedra, one B9 polyhedron, one B10 polyhedron, one irregularly shaped B16 polyhedron in which only 10.7 boron atoms are available because of partial occupancies and 10 bridging sites. All polyhedron units and bridging site atoms interconnect each other forming a three-dimensional boron framework structure. Sc atoms reside in the open spaces in the boron framework structure.
