Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In a patent, Application of 141-30-0, molecular formula is C4H2Cl2N2, introducing its new discovery. Application of 141-30-0

Two ternary ligands consisting of two 2,2?:6?,2??- terpyridines and one N4-quadridentate mu2,eta2- bridging ligand were synthesized. The N4 bridge is 1,4-bis(2-pyridyl)phthalazine in ligand 1, and 3,6-bis(2-pyridyl)pyridazine in ligand 2. Two Co(ii) dinuclear complexes [(1)Co2(mu-OH)]3+ and [(2)Co 2(mu-OH)]3+, and one Ni(ii) dinuclear complex [(1)Ni2(mu-Cl)]3+ were obtained. In the crystal structures of [(1)Co2(mu-OH)]3+ and [(1)Ni 2(mu-Cl)]3+, two pyridine rings are twisted around the pyridine-phthalazine bonds to avoid steric repulsion between the hydrogen atoms. The pyridine rings also showed a significant tilt from the octahedral coordination plane, which causes the large positive shift of the first reduction potentials. Upon the addition of a proton, the cobalt dinuclear complexes can release one cobalt ion selectively, and the dinuclear complexes can be easily restored by the addition of a tertiary amine.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst does not appear in the overall stoichiometry of the reaction it catalyzes. “Application of 141-30-0
