According to experimental data, the complex can be characterized in the solid state as mononuclear, with a distorted octahedral stereochemistry. The distorted octahedral stereochemistry adopted by the complex was further confirmed by X-ray structure analysis of the current study, which consists of a six-coordinate Zn atom in a distorted octahedral environment constructed from two N atoms and four O atoms. The title compound crystallizes in the monoclinic space group C 2/c with a = 27.9248(18) Å, b = 8.5941(4) Å, c = 14.8344(11) Å, α = 90°, β = 108.651(5), γ = 90°, Z = 4. The molecular structure and geometry were also optimized using the B3LYP density functional theory method employing the 6-31G (d) basis set. Molecular electrostatic potential, frontier molecular orbital analysis, nonlinear optical properties and natural bond analysis for the title molecule are also described from the computational process.</dc:description><dc:publisher>DE GRUYTER POLAND SP Z O O</dc:publisher><dc:date>2014</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/15423</dc:identifier><dc:identifier>https://doi.org/10.1515/hc-2013-0160</dc:identifier><dc:identifier>0793-0283</dc:identifier><dc:language>en</dc:language><dc:relation>Heterocyclic Communications</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/15423</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
