Bis(pentamethylcyclopentadienyl)iron Specification

The Bis(pentamethylcyclopentadienyl)iron, with the CAS registry number of 12126-50-0, is also known as Ferrocene, decamethyl-. This chemical's molecular formula is C20H30Fe and molecular weight is 326.3005. What's more, its systematic name is called Iron; 1, 2, 3, 4, 5-pentamethylcyclopenta-1, 3-diene; 1, 2, 3, 4, 5-pentamethylcyclopentane. And Bis(pentamethylcyclopentadienyl)iron is a sandwich compound. It is similar in structure and bonding to Ferrocene, but with a methyl group on each of the carbons of the Cp rings. In addition, it must be stored in airtight containers filled with inert gases and placed in a dry place at room temperature. Meanwhile, it should be avoided contact with light, air, oxidant, moisture.

Physical properties about Bis(pentamethylcyclopentadienyl)iron are: (1)ACD/LogP: 4.64; (2)# of Rule of 5 Violations: 0; (3)#H bond acceptors: 0; (4)#H bond donors: 0; (5)#Freely Rotating Bonds: 0; (6)Polar Surface Area: 0 Å2; (7)Flash Point: 44.4 °C; (8)Enthalpy of Vaporization: 38.99 kJ/mol; (9)Boiling Point: 170.2 °C at 760 mmHg; (10)Vapour Pressure: 1.97 mmHg at 25 °C.

Preparation: Bis(pentamethylcyclopentadienyl)iron is prepared in the same manner as Ferrocene from Pentamethylclyclopentadiene. This method may be used to produce other decamethylcyclopentadienyl sandwich compounds. The product can be purified by sublimation.
