Pentanuclear cluster of palladium(II) bridged by telluride ions: synthesis and crystal structure of [Pd5(µ3-Te)4(Ph2PCH2CH2PPh2)4]2+

Abstract

A pentanuclear palladium(II) cluster [Pd₅(µ₃-Te)₄(dppe)₄]²⁺[dppe = 1,2-bis(diphenylphosphino)ethane] has been synthesized and characterized by an X-ray diffraction study; the cluster comprises two dinuclear [Pd₂Te₂(dppe)₂] units the PdP₂Te₂ co-ordination planes of which fold along the common Te ⋯ Te axis with the four telluride ions of the two dinuclear units additionally co-ordinated to a central palladium(II).
