Abstract

The reaction of N-methyl-2-mercaptoimidazole (methimazole, Hmt) with NaN(SiMe3)2, [PdCl2(L)3] (L = PPh3, NCMe) and SnCl4 provides the novel tetrabicyclo[3.3.3.3.0] lantern compound [PdSn(μ-mt)4Cl 2] (1) in which a dative PdII→SnIV bond is housed within the cage structure. Single-crystal X-ray diffraction analysis reveals a Pd-Sn separation of 2.605(1) Å in this compound, and the cation [PdSn(mt)4Cl]+ was detected by ESI-MS analysis of an acetonitrile solution of [PdSn(μ-mt)4Cl2]. Quantum chemical analysis of the Pd-Sn bonding situation revealed predominant electrostatic interactions between the positively charged Sn and the negatively charged Pd atom.
