COA of Formula: C6H7N3O2SOn March 1, 2005, Du, Miao; Jiang, Xiu-Juan; Zhao, Xiao-Jun published an article in Acta Crystallographica, Section E: Structure Reports Online. The article was 《Diaquabis(2,5-di-3-pyridyl-1,3,4-oxadiazole)dithiocyanatomanganese(II): a three-dimensional supramolecular network formed through O-H···N and C-H···S interactions》. The article mentions the following:
Crystals of the neutral mononuclear title complex are triclinic, space group P1̅, with a 8.1951(19), b 8.762(2), c 10.619(3) Å, α 82.472(3), β 77.181(3), γ 79.873(3)°; Z = 1, dc = 1.494; R = 0.035, w(F2) = 0.099 for 2540 reflections. The structure is centrosym.; the MnII atom lies on an inversion center and is six-coordinate (MnN4O2), with an octahedral geometry comprising two trans monodentate 2,5-di-3-pyridyl-1,3,4-oxadiazole ligands, two thiocyanate ligands and two bound H2O mols. Intermol. O-H···N H bonds between these monomeric units result in two-dimensional supramol. layers with a parallel arrangement, which are stabilized by intralayer aromatic stacking and further extended to a three-dimensional network via interlayer weak C-H···S interactions. The results came from multiple reactions, including the reaction of 4-Amino-2-(methylthio)pyrimidine-5-carboxylic acid(cas: 771-81-3COA of Formula: C6H7N3O2S)
4-Amino-2-(methylthio)pyrimidine-5-carboxylic acid(cas: 771-81-3) belongs to anime. Left-handed and right-handed forms (mirror-image configurations, known as optical isomers or enantiomers) are possible when all the substituents on the central nitrogen atom are different (i.e., the nitrogen is chiral). With amines, there is extremely rapid inversion in which the two configurations are interconverted.COA of Formula: C6H7N3O2S
