Spectrophotometric and photocatalytic studies of H-bonded charge transfer complex of oxalic acid with imidazole: single crystal XRD, experimental and DFT/TD-DFT studies

Abstract

The photocatalytic activity of a new CT complex was tested. Spectrophotometric studies were performed to understand its formation through N⁺–H⋯O⁻ hydrogen bonding, and the structure was confirmed by single crystal XRD.
