Three crystalline hemi-hydrate, channel solvates (classified as solvates from here on) of finasteride (N-(1,1-di-methylethyl)-3-oxo-4-aza-5 alpha-androst-1-ene-17beta-carboxamide) have been obtained and fully characterized. The acetone, methyl ethyl ketone (MEK), and toluene solvates of finasteride, described herein, were found to be isostructural and(More)
Single crystals of Li(6)CuB(4)O(10) have been synthesized, and its crystal structure has been determined. Li(6)CuB(4)O(10) crystallizes in the non-centrosymmetric triclinic space group P1 (No. 1). The structure consists of isolated [CuB(4)O(10)](6)(-) polyanions that are bridged by six LiO(4) tetrahedra. Li(6)CuB(4)O(10) is a congruently melting compound.(More)
A solid solution was found to exist in the quaternary Li(2)O-MgO-V(2)O(5)-MoO(3) system between the two phases Mg(2.5)VMoO(8) and Li(2)Mg(2)(MoO(4))(3). Both Mg(2.5)VMoO(8) and Li(2)Mg(2)(MoO(4))(3) are isostructural with the mineral lyonsite, and substitution according to the formula square(1/4-x/6)Li(4x/3)Mg(15/4-7x/6)V(3/2-x)Mo(3/2+x)O(12) (0 < or = x <(More)
Large single crystals (Φ 5 × L 33 mm) of hematite (R-Fe2O3) have been grown using a CaFe4O7based solvent and 8 bar of oxygen in a four-mirror optical floating zone furnace in the traveling solvent zone configuration. The crystals grow along the [001] direction, are of excellent quality, and contain no residual Ca contamination from the solvent.
Low-temperature barium metaborate â-BaB2O4 has been grown using a LiBa2B5O10-based solvent in a four-mirror optical floating zone furnace with a traveling solvent zone configuration. The â-BaB2O4 rods grown are composed of several different crystal domains, ranging from 100 μm to 1 mm in diameter, and lithium, a component of the flux, was present only at(More)
Single crystals of Pb2CuB2O6 were grown from a PbO/CuO/B2O3 flux, and crystallize in a monoclinic cell of dimensions a = 5.6311(6), b = 8.7628(9), c = 6.2025(6) Å, and b = 115.7060(10)8 with Z = 2; the space group is P21/c (no. 14). The structure was determined from 662 unique reflections and refined to the final residuals R1 = 0.0217, wR2 = 0.0586. The(More)
Crystal-structure determination using X-ray diffraction from single crystals is a well-developed technique (1). A single crystal structure provides full structural characterization of the form at the atomic scale. The main drawback to single crystal diffraction is the need to grow a sufficiently large and defect-free crystal for analysis, which is not(More)
Bi2Cu5B4O14 crystallizes in the noncentrosymmetric triclinic space group P1 (No. 1) with cell parameters a 1⁄4 10.1381(11) Å, b 1⁄4 9.3917(11) Å, c 1⁄4 3.4566(4) Å, a 1⁄4 105.570(2)1, b 1⁄4 92.275(2)1, g 1⁄4 107.783(2)1, Z 1⁄4 1 and R1 1⁄4 0.0401 and wR2 1⁄4 0.0980. It is a layered structure that is built up from sheets of rectangular CuO4 and trigonal BO3(More)
Mg(2.56)V(1.12)W(0.88)O(8) crystals were grown from a MgO/V(2)O(5)/WO(3) melt. X-ray single-crystal diffraction studies revealed that it is orthorhombic with space group Pnma, a = 5.0658(5) A, b = 10.333(1) A, c = 17.421(2) A, Z = 6, and is isostructural with Mg(2.5)VMoO(8). Raman spectra are reported, and the assignment of the Raman bands is made by(More)
