Abstract	Transfer of the first electron from (Ph3P)6Cu6H6 to Cp2Fe(+) is fast (k > 106 L?mol(-1)?s(-1)). Transfer of a second electron to the same oxidant has a much lower thermodynamic driving force and is considerably slower, with k = 9.29(4) × 103 L?mol(-1)?s(-1). The second oxidation leads to the formation of [(Ph3P)6Cu6H5](+). The structure of [(Ph3P)6Cu6H5](+) has been confirmed by its conversion back to (Ph3P)6Cu6H6 and by microanalysis; X-ray diffraction shows that the complex is a bitetrahedron in the solid state. [(Ph3P)6Cu6H5](+) can also be prepared by treating (Ph3P)6Cu6H6 with MeOTf. With less than one equiv of Cp2Fe(+) as oxidant, (Ph3P)6Cu6H6 gives [(Ph3P)7Cu7H6](+) as the major product; X-ray diffraction shows a Cu6 octahedron with one face capped by an additional Cu. [(Ph3P)7Cu7H6](+) can also be prepared by treating (Ph3P)6Cu6H6 with [Cu(CH3CN)4]+ (along with one equiv of Ph3P), and can also be converted back to (Ph3P)6Cu6H6 with base/H2.

The number of electrons in each of copper's shells is 2, 8, 18, 1 and its electron configuration is [Ar]3d¹⁰ 4s¹. The copper atom has a radius of 128 pm and a Van der Waals radius of 186 pm. Copper was first discovered by Early Man prior to 9000 BC. In its elemental form, copper has a reddish-orange metallic and lustrous appearance. Of all pure metals, only silver Elemental Copper has a higher electrical conductivity. The origin of the word copper comes from the Latin word 'cuprium' which translates as "metal of Cyprus," as the Mediterranean island of Cyprus was known as an ancient source of mined copper..
