Materials Data on ClF5 by Materials Project

ClF5 crystallizes in the orthorhombic Cmc2_1 space group. The structure is zero-dimensional and consists of four ClF5 clusters. Cl is bonded in a square pyramidal geometry to five F atoms. There are a spread of Cl–F bond distances ranging from 1.63–1.75 Å. There are four inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Cl atom. In the second F site, F is bonded in a single-bond geometry to one Cl atom. In the third F site, F is bonded in a single-bond geometry to one Cl atom. In the fourth F site, F is bonded in a single-bond geometry to one Cl atom.

NASA NTRS1971

Toxic Hazards Research Unit

The activities of the Toxic Hazards Research Unit (THRU) for the period of June 1970 through May 1971 reviewed. Modification of the animal exposure facilities primarily for improved human safety but also for experimental integrity and continuity are discussed. Acute toxicity experiments were conducted on hydrogen fluoride (HF), hydrogen chloride (HCl), nitrogen dioxide (NO2), and hydrogen cyanide (HCN) both singly and in combination with carbon dioxide (CO). Additional acute toxicity experiments were conducted on oxygen difluoride (OF2) and chlorine pentafluoride (ClF5). Subacute toxicity studies were conducted on methylisobutylketone and dichloromethane (methylene dichloride). The interim results of further chronic toxicity experiments on monomethylhydrazine (MMH) are also described.

Toxic Hazards Research Unit annual technical report, 1972

The activities of the Toxic Hazards Research Unit (THRU) for the period of June 1971 through May 1972 are reviewed in this report. Acute inhalation toxicity experiments were conducted on hydrogen chloride (HCl) gas and aerosol, ethyl bromide (C2H5Br), hydrogen bromide (HBr), hydrogen sulfide (H2S), ammonia (NH3), chlorine (CL2), and silane (SiH4). Subacute toxicity studies were conducted on chlorine pentafluoride (ClF5), dichloromethane (CH2Cl2) and coal tar volatiles. Further toxicity studies of subacute and chronic responses to inhaled monomethylhydrazine (MMH) are also described.

Space Defense Initiative technologies and hardware can help resolve certain space exploration initiative weight and performance issues

The use of Space Defense Initiative (SDI) technologies and hardware in solving Space Exploration Initiative (SEI) problems is presented. The topics discussed include the following: Aerojet programs, SDI's technical focus, SDI technology weight savings, realized benefits, composite technologies, the Advanced Liquid Axial Stage (ALAS), propellant and pressurant tanks, lightweight engines, high performance helium tanks, hoop and helical fibers, ALAS's advanced carbon composite structure, and CLF5 performance issues. The discussion is presented in viewgraph form.
