Synthesis and molecular structure of the sodium arsanediyl zincate [(thf)Na]2[(EtZn)6(AsSiiPr3)4]

The reaction of NaAs(H)SiiPr3 with ZnEt2 in the presence of additional triisopropylsilylarsane yields the heterobimetallic complex [(thf)Na]2 [(EtZn)6(AsSiiPr3)4] (1) in the shape of red prisms. The Na–As and Zn–As bond lengths show values of 301/309 pm and between 247 and 260 pm, respectively.
