Crystal Structures of New Ammonium 5-Aminotetrazolates
The crystal structures of three salts of anionic 5-aminotetrazole are described. The tetramethylammonium salt (P[Formula: see text]) forms hydrogen-bonded ribbons of anions which accept weak C-H⋯N contacts from the cations. The cystamine salt (C2/c) shows wave-shaped ribbons of anions linked by hydrogen bonds to screw-shaped dications. The tetramethylguanidine salt (P21/c) exhibits layers of an...
متن کاملCrystal structure of (OC)5W(μ-dppe)W(CO)5
The centrosymmetric title complex, [μ-ethane-1,2-diylbis(di-phenyl-phosphane)-κ2P:P']bis-[penta-carbonyl-tungsten(0)], [W2(C26H24P2)(CO)10], consists of two W(CO)5 moieties bridged by a bis-(di-phenyl-phosphan-yl)ethane (dppe) ligand. The W0 atom has a slightly distorted octa-hedral coordination environment consisting of 5 carbonyl ligands and one P atom from the bridging dppe ligand with the n...
متن کاملTemperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures
Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...
متن کاملNew G-protein-coupled receptor crystal structures: insights and limitations.
G-protein-coupled receptors (GPCRs) constitute a large family of structurally similar proteins that respond to a chemically diverse array of physiological and environmental stimulants. Until recently, high-resolution structural information was limited to rhodopsin, a naturally abundant GPCR that is highly specialized for the detection of light. Non-rhodopsin GPCRs for diffusible hormones and ne...

Lady Manners School Bakewell, Corpus Christi College, Oxford, and St. Mary's Hospital. He graduated B.A. (Physiology) in 1960 and M.A., B.M., B.Ch., in 1964. After qualification his first appointment was to the orthopaedic unit at St. Mary's and this post produced a life-long enthusiasm for the speciality. Further posts at St. Mary's followed and he worked at Coventry, Oxford, Liverpool and Edi...
