Qiu, Zhi-Hui published the artcilecatena-Poly[[diaquamanganese(II)]-di-μ-pyridine-3-sulfonato-κ2N:O;κ2O:N], Quality Control of 636-73-7, the publication is Acta Crystallographica, Section E: Structure Reports Online (2008), 64(6), m765, m765/1-m765/7, database is CAplus and MEDLINE.
In the title polymeric complex, [Mn(C5H4NO3S)2(H2O)2]n, the Mn atom is located on a center of inversion and is coordinated by two O atoms and two N atoms derived from four different pyridine-3-sulfonate (pySO3) ligands, and two O atoms derived from two H2O mols. in a distorted trans-N2O4 octahedral geometry. The metal atoms are bridged by the pySO3 ligands to form a 1-dimensional chain. The chains are further connected into a three-dimensional architecture via H bonds. Crystallog. data and at. coordinates are given.
