Abstract.Zn (C6HIlN3)

Crystal Structure of 4-(2-chlorophenyl)-3-(4-methoxyphenyl)-1,2,4-triazole-5-thione

“…The bond lengths and bond angles are listed in Table 3. The bond lengths and bond angles of the triazole ring are comparable with related structures (GROENEVELD, VOS, GORTER and HAASNOOT, 1982;KOKKU and RENIZEPERIS, 1975). The triazole ring is planar with the maximum deviation of -0.013(1) Å for atom C3.…”

Macrocyclic Metalloenediynes of Cu(II) and Zn(II): A Thermal Reactivity Comparison

“…Unlike Cu(II), Zn(II) is d 10 and, therefore, has different geometric structural preferences depending upon the nature of the binding ligands. In chemical structures, Zn(II) is frequently 4-6 coordinate and can adopt geometries ranging from planar [25][26][27][28][29][30] or tetrahedral [31][32][33][34][35][36][37] for coordination number 4 to square pyramidal [38][39][40][41][42] or trigonal bipyramidal [43][44][45][46] for 5-coordinate complexes or psuedooctahedral [47][48][49][50][51] for hexacoordinate centers. Most commonly, the d 10 electronic configuration will result in a 4-coordinate, tetrahedral structure unless otherwise constrained by the con- formational rigidity of the ligand.…”

“…1, the tridentate ligands coordinate to the Zn atom through two phenolic hydroxy O atoms and two isothiocyanate N atoms, forming a distorted tetrahedral geometry around the metal ion. The isothiocyanate group was not used as a bridged ligand, in the same way to the other Zn complexes with the ligand of isothiocyanate (Li, 2007;Zhang & Wang, 2007;Groeneveld et al, 1982).…”
