Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1603-91-4, Name is 4-Methylthiazol-2-amine, Application In Synthesis of 4-Methylthiazol-2-amine.
Starting from closely related metal-ligand combinations, completely different oligomeric metal clusters are synthesized. Whereas, picoline-tetrazolylamide HL1 (1) and zinc or nickel acetate afforded [2 ¡Á 2] grids [M4(L1)8 (2), slightly different N-(2-methylthiazole-5-yl)-thiazole-2-carboxamide HL2 (5a) and nickel acetate yielded the monometallic complex [Ni(L2)2(OH2)2] (6). In contrast, reaction of 5a with zinc acetate produced the tetrametallic zinc cluster [Zn4O(L2)4(OAc)2] (7). Even more surprising, when 3-methyl-substituted HL3 (5b) instead of 2-methyl-substituted HL2 (5a) was allowed to react under identical conditions with zinc acetate, the cluster [Zn4O(L3)4Cl2] (8) crystallized from dichloromethane. Clusters 7 and 8 are isostructural. As for 7, in 8 two of the edges of the tetrahedron of zinc ions are doubly bridged, two are singly bridged, and the other two are nonbridged. On the other hand, when iron(II) acetate under aerobic conditions was allowed to react with 5a, the unprecedented complex [{Fe3O(L2)2(OAc)4}2o] (9) was isolated. Cluster 9 is composed of two trimetallic, triangular mu3-O2–centered [Fe3O(L2)2(OAC)4]+ modules, linked by an almost linear mu2- O2- bridge. The Moessbauer spectrum together with cyclic voltammetric and square-wave voltammetric measurements of 9 are reported, and 6-9 were characterized unequivocally by single-crystal x-ray structure analyses.
