Abstract

Abstract : Reaction of ( Ar′ NacNac)ZnI with K/Hg gave {( Ar′ NacNac)Zn}2 Hg (1 ), the first example of a bond between two different Group 12 metals. DFT and QTAIM analyses suggest a formal Zn(i )–Hg(0)–Zn(i ) linkage;1 reacts with I2, FpI or Fp2 to give products of the type ( Ar′ NacNac)ZnX (X = I or Fp; Fp = CpFe(CO)2 ). Abstract : Reaction of ( Ar′ NacNac)ZnI with potassium/mercury amalgam gave the trimetallic compound {( Ar′ NacNac)Zn}2 Hg (1 ) containing a Zn–Hg–Zn unit and the first example of a bond between two different Group 12 metals; DFT and QTAIM analyses suggest that 1 is best described as two formally Zn(i ) atoms with a Hg(0) atom positioned between them; reactions of1 with stoichiometric I2, FpI or Fp2 gave addition products of the type ( Ar′ NacNac)ZnX (X = I, Fp) and Hg. Ar′ NacNac = HC{C(Me)N(2, 6-C6 H3 i Pr2 )}2 ; Fp = CpFe(CO)2 .
