• General Description: 2,2'-DIPYRIDYLAMINE (dpa) is a bidentate ligand used in the synthesis of coordination compounds, where it contributes to the formation of complexes with increased structural dimensionality, as demonstrated in the study involving [Cu(dpa)2][HgCl3]2. The ligand facilitates interactions between metal centers, such as Cu(II) and Hg(II), leading to the formation of polynuclear or extended structures. Its role in coordination chemistry highlights its utility in constructing frameworks with potential magnetic properties.

Cu(NN)₂Cl₂ and Cu(NNN)Cl₂ and HgCl ₂ building blocks in the synthesis of coordination compoundsX-ray studies and magnetic properties

The research investigates the synthesis and structural characterization of a series of coordination compounds containing Cu(N–N)2Cl2, Cu(N–N–N)Cl2, and HgCl2 building blocks. The purpose of this study is to explore the structural dimensionality and magnetic properties of these compounds, which are synthesized using various ligands such as bis(pyrazol-1-yl)methane (bpzm), bis(3,5-dimethylpyrazol-1-yl)methane (bdmpzm), 2,2-dipyridylamine (dpa), 5,6-diphenyl-3-(2-pyridyl)-1,2,4-trazine (dppt), 2,2'-bipyridine (bipy), and 2,2:6,2'-terpyridine (terpy). The researchers observed an increase in structural dimensionality for compounds [Cu(bpzm)2][HgCl4], [Cu(dpa)2][HgCl3]2, and [Cu(terpy)(m-Cl)HgCl3], and conducted magnetic measurements on complexes [Cu(bpzm)2][HgCl4] and [Cu(terpy)(m-Cl)HgCl3]. The study concludes that the HgCl2 moiety can accept chloride ligands from the Cu(II) centers to form binuclear or polynuclear complexes, and in the case of [Cu(terpy)(m-Cl)HgCl3], there is very weak antiferromagnetic interaction of copper centers in the one-dimensional chain.
