Tantalum(V) chloride, also known as tantalum pentachloride, is an inorganic compound with the formula TaCl 5.It takes the form of a white powder and is commonly used as a starting material in tantalum chemistry.
Tantalum(III) chloride or tantalum trichloride is non-stoichiometric chemical compound with a range of composition from TaCl 2.9 to TaCl 3.1 [2] Anionic and neutral clusters containing Ta(III) chloride include [Ta 6 Cl 18] 4− and [Ta 6 Cl 14](H 2 O) 4. [3] Structure of edge-capped octahedral clusters such as Ta 6 Cl 18 2−. [4]
De Marignac was the first to produce the metallic form of tantalum in 1864, when he reduced tantalum chloride by heating it in an atmosphere of hydrogen. [25] Early investigators had only been able to produce impure tantalum, and the first relatively pure ductile metal was produced by Werner von Bolton in Charlottenburg in 1903.
Trimethylphosphine was introduced by vapour transfer to dichlorotrimethyltantalum frozen in a liquid nitrogen bath, resulting in the seven-coordinate bisphosphine complex. The complex, like 2,2'-Bipyridyldichloro(trimethyl)-tantalum(V), resembles a capped trigonal prism, but with a trimethylphosphine ligand capping instead of a chloride.

Tantalum alkylidene complexes arise by treating trialkyltantalum dichloride with alkyl lithium reagents. This reaction initially forms a thermally unstable tetraalkyl-monochloro-tantalum complex, which undergoes α-hydrogen elimination, followed by alkylation of the remaining chloride.

The team identified a 2.2-second SF activity in a volatile chloride portraying eka-tantalum properties, and inferred that the source of the SF activity must have been element 105. [ 20 ] In June 1970, JINR made improvements on their first experiment, using a purer target and reducing the intensity of transfer reactions by installing a ...
