The precursor complexes of composition [Cu(bpy)2(H2O)](PF6)2 1 and [Cu(bpy)2(NCS)](PF6) 2 (bpy = 2,2′-bipyridine) were initially prepared and characterized using spectroscopic (IR, UV-vis, ESR, Emission) along with their mass, elemental analysis, and single crystal X-ray crystallographic data. Complex 2 is linked with a known complex Ru(bpy)2(NO3)2 prepared in situ. The resulting heterobimetallic complex of composition [Cu(bpy)2(μ-NCS)Ru(bpy)2(NO3)](PF6)2 3 was isolated and characterized by its spectroscopic, mass, and elemental analysis data and its geometry is optimized without any constraint with plane-wave ab initio density functional theory using solid state package Abinit. The emission and electrochemical properties of these complexes are studied. The multiresponsive chemosensor property of complex 3 for Hg(II) ions as compared to Cd(II), Pb(II) and Ag(I) ions is monitored using UV-vis and fluorescence titrations.
