A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 21436-03-3, Name is (1S,2S)-Cyclohexane-1,2-diamine, molecular formula is C6H14N2. In a Article，once mentioned of 21436-03-3, SDS of cas: 21436-03-3
The reaction of K3[Cr(CN)6] and the copper(II) bis-diamino complex of the ligand 1,3-diaminopropane (tn) led to the new cyanide-bridged 3D polymer {[(Cu(tn)2)3(Cr(CN) 6)][Cr(CN)6]}? (1). Crystallographic data for 1: trigonal space group R3, a = b = 15.4908(11), c = 16.7699(13) A, Z = 3, V = 3485.0(4) A3. By the same reaction using trans-cyclohexane-(1R,2R)-diamine [1R,2Rchxn] or trans-cyclohexane-(1S,2S)- diamine [1S,2Schxn] as ligands, the chiral 1D polymers {[Cu(1R,2Rchxn) 2]3[Cr(CN)6]2·4.75H 2O}? (2) and {[Cu(1S,2Schxn)2] 3[Cr(CN)6]2·4.25H2O} ? (3), respectively, were obtained. 2 and 3 are isostructural and crystallize in the triclinic space group P1, with a = 8.5421(6), b = 12.6379(9), c = 16.1571(11) A, alpha = 104.594(5), beta = 98.425(6), gamma = 97.440(5), Z = 1, V = 1644.3(2) A3 for 2, and a = 8.5435(8), b = 12.6309(12), c = 16.1711(17) A, alpha = 104.632, beta = 98.429(8), gamma = 97.375(8), Z = 1, and V = 1645.1(3) A3 for 3. The complexes have been characterized by X-ray crystallography, IR, and magnetic susceptibility measurements. The chirality of 2 and 3 has been confirmed by circular dichroism measurements in the solid state. From the magnetic point of view, 1 shows 3D ferromagnetic ordering at ca. 4K, and 2 shows a weak intrachain ferromagnetic exchange, as a result of magnetic orbital orthogonality between Cr(III) and Cu(II) in the chain, with very long Cu-N(cyano) distances (2.665(5) and 2.671(5) A) due to the long Jahn-Teller axis of the copper(II) ions.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.SDS of cas: 21436-03-3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 21436-03-3, in my other articles.
