The first (which has two forms, one purple and one green) is a rare example of thorium in the formal +3 oxidation state. [35] [34] In the derivative [Th III {η 5-C 5 H 3 (SiMe 3) 2} 3], a blue paramagnetic compound, the molecular geometry is trigonal planar around the thorium atom, which has a [Rn]6d 1 configuration instead of the expected [Rn ...
The first (which has two forms, one purple and one green) is a rare example of thorium in the formal +3 oxidation state. [2] [1] In the derivative [Th III {η 5-C 5 H 3 (SiMe 3) 2} 3], a blue paramagnetic compound, the molecular geometry is trigonal planar around the thorium atom, which has a [Rn]6d 1 configuration instead of the expected [Rn]5f 1.
The simplest of the cyclopentadienyls are Th(C 5 H 5) 3 and Th(C 5 H 5) 4: many derivatives are known. The former (which has two forms, one purple and one green) [71] is a rare example of thorium in the formal +3 oxidation state; [72] a formal +2 oxidation state occurs in a derivative. [73]
Thorium(IV) nitrate is a chemical compound, a salt of thorium and nitric acid with the formula Th(NO 3) 4. A white solid in its anhydrous form, it can form tetra- and penta hydrates . As a salt of thorium it is weakly radioactive .

Thorium trichloride is a binary inorganic compound of thorium metal and chlorine with the chemical formula ThCl 3. [1] [2] [3] Synthesis. The compound can be prepared ...
Thorium(IV) iodide (Th I 4) is an inorganic chemical compound composed of thorium and iodine. It is one of three known thorium iodides, the others being ThI 3 and ThI 2.
ThCl 4 was an intermediate in the original isolation of thorium metal by Jons Jacob Berzelius. [2] Thorium(IV) chloride can be produced in a variety of ways. One method is a carbothermic reaction, 700 °C to 2600 °C, involving thorium oxides and carbon in a stream of chlorine gas: ThO 2 + 2 C + 4 Cl 2 → ThCl 4 + 2 CO
