Ca₂LiC₃H: A new complex carbide hydride phase grown in metal flux

Lang, David A.,Zaikina, Julia V.,Lovingood, Derek D.,Gedris, Thomas E.,Latturner, Susan E.

, p. 17523 - 17530 (2010)

The reaction of carbon and CaH₂ in a calcium/lithium flux mixture produces crystals of the new compound Ca₂LiC₃H. This phase forms with a new structure type in tetragonal space group P4/mbm (a = 6.8236(1) A, c = 3.7518(1) A, Z = 2, R₁ = 0.0151). This is a stuffed variant of the Cs₂(NH₂)N₃ structure, containing hydride anions in octahedral sites; the structure determination by single-crystal X-ray diffraction surprisingly allowed the hydrogen to be detected. The Ca₂LiC₃H structure also features the rarely seen C₃^4- carbide anion; the protolysis reaction of this compound with ammonium chloride produces C ₃H₄. The electronic properties of Ca₂LiC ₃H were studied by quantum-chemical calculations including band structure and electron localization function (ELF) analysis; the phase is a charge-balanced semiconductor with a calculated band gap of 0.48 eV. This is in agreement with ⁷Li, ¹³C, and ¹H MAS NMR data, which show resonances in the ionic region instead of the Knight shifted region. ELF analysis of the theoretical nonhydrided Ca₂LiC₃ structure confirms the ability of these calculations to properly locate hydrides and supports the structural model based on X-ray diffraction data.

Production of calcium carbide from fine biochars

, p. 8480 - 8483 (2010)

Rising from the ashes: Fine chars produced from biomass can be used as a feedstock for the production of CaC₂ in an autothermal process that operates at a temperature 500 °C lower than the traditional electric arc process and with greatly reduced reaction time (see scheme for the reaction of CaO and C forming CaC₂).

Use of nitric oxide-releasing agents to treat impotency

-

, (2008/06/13)

A method of treatment for impotency is provided. The method involves the administration of nitric oxide by a nitric oxide-releasing agent capable of providing a penile erection-inducing amount of nitric oxide to the corpus cavernosum of the penis of an impotent male animal. Also provided is a nitric oxide delivery means for use in the method.

On the coexistence of tetragonal and monoclinic CaC₂: Structural and spectroscopic studies on alkaline earth metal acetylides, MC₂ (M = Ca, Sr, Ba)

Reckeweg, Olaf,Baumann, Andreas,Mayer, Hermann A.,Glaser, Jochen,Meyer, H. -Jürgen

, p. 1686 - 1692 (2008/10/08)

The alkaline earth acetylides CaC₂, SrC₂ and BaC₂ can be considered to occur in three polymorphic structures each. The monoclinic low-temperature form, the tetragonal form, and the cubic high-temperature form. No deviation from axial symmetry is obtained for the C₂^2- ions in the tetragonal structure determinations, as confirmed by X-ray single-crystal structures and ¹³C MAS NMR studies. The CaC₂ samples prepared by us were always a mixture of monoclinic and tetragonal phase. Their Raman spectra exhibited two distinct C₂ streching vibrations. Problems arising from the coexistence of these two phases for the interpretation of ¹³C MAS NMR spectra are discussed.
