Rhenium polyhydride complexes that contain the tripodal phosphine CH3C(CH2PPh2)3 (triphos). Inorganic Chemistry, 31 (12), . Rhenium polyhydride complexes that contain the tripodal phosphine CH3C(CH2PPh2)3 (triphos).

Rareearth element Properties of the metals: As noted above, the rareearth elements—especially the lanthanides—are quite similar. They occur together in nature, and their complete separations are difficult to achieve. However, there are some striking differences, especially in the physical properties of the pure metallic elements. For example, their melting points differ by nearly a ...

Abstract. Experimental data are presented on the effect of introduction of up to 12 wt % Re on the structure and properties of ZhStype complexly alloyed casting nickel superalloys intended for the blades of modern aviation gasturbine engines. Rhenium alloying is found to increase the temperature of onset of melting of the alloys and...

The crystal structures of all six complexes were determined by Xray crystal diffraction analysis, showing that they have similar molecular structures, being mononuclear carbonyl complexes. In each of these complexes, the Re atom is η 5coordinated to the cyclopentadienyl ring.

Rhenium is a metallic element that has a very high tensile strength (80,000psi), high modulus of elasticity, is virtually insoluble in hydrochloric acid and does not oxidize or corrode in saltwater. In addition it has the widest range of valences of any element and it retains its .

Enormous coppergold deposit in Alaska contains enough of this superalloy metal to supply global needs for 40 years. With a melting point of 5,756 degrees Fahrenheit and a heatstable crystalline structure, rhenium is extremely resistant to both heat and wear.
