In this research, a new flower‐like Ni_0.77/Co_0.23– benzene–1,3,5–tricarboxylate (BTC) bimetallic organic framework (Ni/Co–BTC BMOF) is synthesized via the cathodic electrosynthesis (CE) method, based on nickel and cobalt metals and BTC linker. The synthesized BMOF is characterized by several methods, including Fourier transform infrared spectroscopy (FT‐IR), powder X‐ray diffraction (PXRD), field emission scanning electron microscopy (FE‐SEM), and energy dispersive X‐ray analysis (EDX). The catalytic activity of the resulting Ni/Co is evaluated in a one‐pot four‐component reaction of dimedone, aromatic aldehyde, 4–hydroxycoumarin, and ammonium acetate for the synthesis of chromeno[4,3–b]quinolone derivatives under solvent‐free condition. The Ni/Co–BTC BMOF catalyst showed very good activity in the tested reaction, and a wide scope of starting materials gave the desired products in high isolated yields in the presence of the Ni/Co–BTC BMOF catalyst. The recovery of Ni/Co BMOF was achieved by a centrifuge, and it was reused at least six times without any significant decrease in catalytic activity.
