Abstract

Xanthene diiodide reacts with Pd₂(dba)₃ in the presence of TMEDA via a double insertion of Pd into the C−I bonds, yielding the complex [XanPd₂(TMEDA)₂I₂] (1). Treatment of 1 with potassium naphthalenide in the presence of dba and 18C6 led to [Pd₂(dba)₂{K-(18C6)}₂] (2), where two reduced dba ligands span two Pd atoms via olefinic functions. The complex, which can also be readily generated from Pd₂(dba)₃ through reduction, crystallizes as a dimer composed by the interaction of two neighboring [K(18C6)]⁺ units with each other, while the second pair of cations coordinate an additional THF molecule each. The electronic structure of 2 was elucidated by SQUID measurements and DFT calculations.
