Early metal macrocycles as metalloligands: the synthesis and structure of Cp2Zr(µ-SCH2CH2CH2S)2ZrCp2 and its silver complex [{Cp2Zr(µ-SCH2CH2CH2S)2ZrCp2}Ag]BPh4(Cp = C5H5)

Abstract

Reaction of Cp₂ZrMe₂ with propane-1,3-dithiol affords the early metal macrocycle Cp₂Zr(µ-SCH₂CH₂CH₂S)₂ZrCp₂1; X-ray structural data confirm that this species acts as a macrocyclic metalloligand for Ag^I yielding [{Cp₂Zr(µ-SCH₂CH₂CH₂S)₂ZrCp₂}Ag]BPh₄2 in which Ag^I is pseudo-tetrahedrally coordinated by the sulphur atoms of 1.
