Abstract:	The first dinuclear bis(mercaptoimidazolyl)methane metal complex, the lead(II) derivative [Pb₂(Bmm^Me)₅](ClO₄)₄, has been prepared and fully characterized using a combination of analytical and spectroscopic techniques. X-ray crystallography confirmed the presence in the solid state of two dicationic [Pb(Bmm^Me)₂]²⁺ fragments bridged by the fifth Bmm^Me ligand, which uses an unprecedented unidentate:bidentate (μ-κ¹-S:κ²-S,S) coordination mode to link the two metal centers.
