During attempts to synthesize a high-pressure phase of KSr4(BO3)3 using pressures of up to 12 GPa, single crystals of the normal-pressure phase KSr4(BO3)3 with sufficient quality for singlecrystal diffraction experiments could be obtained at 3 GPa and 1300 °C in a Walker-type multianvil apparatus. The single-crystal structure determination verified the published powder diffraction data of KSr4(BO3)3 revealing the non-centrosymmetric space group Ama2 with a = 1104:8(2), b=1199:1(2), c=688:8(2) pm and Z =4. Additionally, IR- and Raman-spectroscopic investigations were performed on single crystals of the compound.

AbstractThe crystal structure of NH4[C(CN)3] has been determined via X-ray single-crystal methods at 203(2) K corroborating earlier results. Additionally, the hydrogen positions have been determined and the Raman spectrum of the title compound recorded on single crystals. The spectroscopic results are compared to those for related compounds.

AbstractThe structures of cetylpyridiniumammonium bromide (CPyB) and cetylquinuclidinium bromide (CQB), two tetraalkylammonium bromide surfactants, are reported. In particular, whereas the structure solution of CPyB was carried out through conventional single-crystal diffractometry, the structure of CQB has been determined by means of powder diffractometry. CPyB crystallizes in
