On October 31, 1992, Cotton, F. Albert; Daniels, Lee M.; Murillo, Carlos A. published an article.Synthetic Route of 636-73-7 The title of the article was Synthesis and x-ray structure of two relatively air-stable chromium(II) 3-pyridinesulfonate compounds. And the article contained the following:
[Cr(pySO3)2(H2O)2]n (I; pySO3H = 3-pyridinesulfonic acid) and Cr(pySO3)2(py)4 (II) were prepared and crystal structures determined I crystallizes as monoclinic, space group P21/c in an extended structure, a 7.723(1), b 12.995(4), c 7.276(3) Å, β 100.24(2)°, Z = 2, R = 0.032, Rw = 0.046. II possesses a mol. structure and crystallizes as monoclinic, space group C2/c, a 17.084(4), b 11.031(3), c 17.828(7) Å, β 112.02(2)°, Z = 4, R = 0.031, Rw = 0.043. The coordination about the Cr atoms is, in both cases, highly distorted. Both compounds are relatively stable towards O in the solid state, especially I. The experimental process involved the reaction of Pyridine-3-sulfonic acid(cas: 636-73-7).Synthetic Route of 636-73-7
