Synthesis, crystal structure, antiproliferative activity, DNA binding and density functional theory calculations of 3‐(pyridin‐2‐yl)‐8‐tert‐butylcoumarin and its copper(II) complex

A Cu(II)–coumarin complex, [CuL2(NO3)2] (2), where L = 3‐(pyridin‐2‐yl)‐8‐tert‐butylcoumarin (1), was synthesized with Cu(NO3)2⋅3H2O and characterized using elemental, infrared and single‐crystal X‐ray diffraction analyses. The crystal structure of 1 shows that all the pyrone, benzene and pyridine r...
