Bis(2‐pyridylthio)methane [bpytm, (pyS) 2 CH 2 ] and complexes of this ligand with Zn II , Hg II , Cu I , and Ag I have been prepared and characterised by elemental analysis, by IR, Raman and 1 H and 13 C NMR spectroscopy, and by X‐ray diffractometry. The ligand is N, N′‐didentate in the Zn II complexes; N‐monodentate in one Hg II complex and N, N′‐bis(monodentate) in the other; N‐mono‐N′, S‐didentate in the Cu I complex; and N, S′‐bis(mono)‐N′, S‐didentate in the Ag I complex. The structural parameters of the ligand in each coordination mode are compared with those of the free ligand and those of the triiodide salt of the protonated ligand.
