Title: Crystal structure of phosphorus-rich ellenbergerite

Abstract

The phosphorus-rich variety of ellenbergerite (Mg{sub 0.61}Ti{sub 0.08}{open_square}{sub 0.31}){sub 2}(Mg{sub 0.52}Al{sub 0.43}{open_square}{sub 0.05})= {sub 12}[SiO{sub 3}(O{sub 0.29}(OH){sub 0.71})]{sub 6} [(P{sub 0.71}Si{sub 0.20}{open_square}{sub 0.09})O{sub 3}OH]{sub 2}(OH){sub 6} was studied by X-ray diffraction and IR spectroscopy. The structure was refined in sp. gr. P6{sub 3}mc to R = 0.0248. The structure of phosphorus-rich ellenbergerite retains the octahedral framework observed in the structures of ellenbergerite, phosphoellenbergerite, ekatite, and a series of structurally related synthetic compounds. The structure of phosphorus-rich ellenbergerite differs from the structure of ellenbergerite primarily in that the Mg and Al cations in the phosphorus-rich variety are disordered in the octahedra of the framework, thereby leading to higher symmetry, and the channels of triangular cross section are occupied predominantly by P tetrahedra.

  • A crystalline form of lithium phosphorus oxynitride, Li{sub 2.88}PO{sub 3.73}N{sub 0.14}, has been prepared by solid state reaction between Li{sub 3}N and LiPO{sub 3} under a flowing N{sub 2} atmosphere. The structure of the oxynitride was refined by Rietveld analysis of neutron powder diffraction data using the orthorhombic unit cell of {gamma}-Li{sub 3}PO{sub 4} with space group Pmnb. High-performance liquid chromatography measurement indicates that most nitrogen substitutes for oxygen to form PO{sub 3}N structural units with small concentrations of P-N=P due to some Li {leftrightarrow} P disorder in the structure. The ionic conductivity of Li{sub 2.88}PO{sub 3.73}N{sub 0.14} ({sigma}{sub 25{degrees}C}more » {approximately} 10{sup {minus}13} S {center_dot} cm{sup {minus}1}) is several orders of magnitude higher than that of {gamma}-Li{sub 3}PO{sub 4} ({sigma}{sub 25{degrees}C} {approximately} 10{sup {minus}18} S {center_dot} cm{sup {minus}1}).« less
  • Powder samples and single crystals of the new complex boride series Cr{sub x}(Rh{sub 1-y}Ru{sub y}){sub 7-x}B{sub 3} (x=0.88-1; y=0-1) have been synthesized by arc-melting the elements under purified argon atmosphere on a water-cooled copper crucible. The products, which have metallic luster, were structurally characterized by single-crystal and powder X-ray diffraction as well as EDX measurements. Within the whole solid solution range the hexagonal Th{sub 7}Fe{sub 3} structure type (space group P6{sub 3}mc, no. 186, Z=2) was identified. Single-crystal structure refinement results indicate the presence of chromium at two sites (6c and 2b) of the available three metal Wyckoff sites, withmore » a pronounced preference for the 6c site. An unexpected Rh/Ru site preference was found in the Ru-rich region only, leading to two different magnetic behaviors in the solid solution: The Rh-rich region shows a temperature-independent (Pauli) paramagnetism whereas an additional temperature-dependent paramagnetic component is found in the Ru-rich region. - Graphical abstract: The new complex boride series Cr{sub x}(Rh{sub 1-y}Ru{sub y}){sub 7-x}B{sub 3} (x=0.88-1; y=0-1) has been synthesized by arc melting the elements under purified argon atmosphere. Beside the 3d/4d site preference within the whole solid solution, an unexpected Rh/Ru site preference was found in the Ru-rich region only, leading to two different magnetic behaviors: The Rh-rich region shows a temperature-independent (Pauli) paramagnetism whereas an additional temperature-dependent paramagnetic component is found in the Ru-rich region. Highlights: Black-Right-Pointing-Pointer Synthesis of a new boride series fulfilling Vegard Acute-Accent s rule. Black-Right-Pointing-Pointer 3d/4d site preference. Black-Right-Pointing-Pointer Unexpected Ru/Rh site preference. Black-Right-Pointing-Pointer Rh-rich region is Pauli paramagnetic. Black-Right-Pointing-Pointer Ru-rich region is Pauli and temperature-dependent paramagnetic.« less
  • Organophosphonates are reduced forms of phosphorous that are characterized by the presence of a stable carbon-phosphorus (C-P) bond, which resists chemical hydrolysis, thermal decomposition, and photolysis. The chemically inert nature of the C-P bond has raised environmental concerns as toxic phosphonates accumulate in a number of ecosystems. Carbon-phosphorous lyase (CP lyase) is a multienzyme pathway encoded by the phn operon in gram-negative bacteria. In Escherichia coli 14 cistrons comprise the operon (phnCDEFGHIJKLMNOP) and collectively allow the internalization and degradation of phosphonates. Here we report the X-ray crystal structure of the PhnH component at 1.77 Angstroms resolution. The protein exhibits amore » novel fold, although local similarities with the pyridoxal 5'-phosphate-dependent transferase family of proteins are apparent. PhnH forms a dimer in solution and in the crystal structure, the interface of which is implicated in creating a potential ligand binding pocket. Our studies further suggest that PhnH may be capable of binding negatively charged cyclic compounds through interaction with strictly conserved residues. Finally, we show that PhnH is essential for C-P bond cleavage in the CP lyase pathway.« less
