摘要

This research article includes synthesizing and structural characterization of an entirely new Cu(II) dicyanamide complex. SXRD analysis reveals the square planar environment of the type {CuN4} in which each asymmetric unit engages in two conventional N–H···O type intermolecular hydrogen bonds and one non-conventional C–H···O type interaction. This complex shows prominent phenoxazinone synthase activity with a high TON of 5.371 × 105 h− 1. DFT calculations accurately reproduce the chemical reactivity and support the proposed mechanisms of the catalyst. Besides, it also shows good antimicrobial activity particularly on Escherichia coli K12 and Bacillus cereus KTWOL4E and found better result on B. cereus (8.11 ± 2.12 mm) than E. coli (7.44 ± 2.17 mm).
