A mononuclear platinum(II) complex with mixed bpy and H4tg鈥?/sup> ligands, [Pt(H4tg-S)2(bpy)]路2H2O (1a; bpy = 2,2鈥?bipyridine and H5tg = 1-thio-尾-d-glucose), is photoluminescent in the solid state and undergoes facile and reversible removal of solvated water molecules accompanied by changes in its absorption and emission wavelengths. The analogous dmbpy complex, [Pt(H4tg-S)2(dmbpy)]路H2O (2a; dmbpy = 4,4鈥?dimethyl-2,2鈥?bipyridine), is also emissive in the solid state, but its absorption and emission spectra remain unchanged after dehydration. X-ray crystallographic analyses revealed that the difference in the chromism of 1a and 2a is due to the difference in their hydrogen-bonding networks, which involve solvated water molecules.
