Structure Solution

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

Synthesis And Crystal Structure

Cl3Ti[N(SiMe2Cl)(SiMe2NH2)] is yielded by reaction of TiCl4 with two molecules ClMe2SiNHSiMe3. A single crystal structure determination (P 21/n, a = 747.12(2), b = 1294.1(3), c = 1496.7(3) pm, β = 90.30(3)°, Z = 4) shows a planar four-membered ring Ti-N-Si-N as the central feature of the monomers formed by a weak coordinative bond of the NH2 group to the Ti atoms. The monomers are connected to give dimers via two Cl bridges linked to the Ti atoms.
