Mono- and dinuclear cadmium(II) complexes based on polybenzimidazole-containing tetradentate and heptadentate ligands: Synthesis, structures and fluorescent properties

Synthesis and crystal structure of a new 2D supramolecular Cd(II) complex with 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone ligand

“…2823(16) and 2.3105(16) Å, respectively, which compare well with those found in some other Cd (II) complexes(Nie et al, 2010;Xue et al, 2012;Sharif and Najafi, 2013; Sun et al, 2013), whose steric configuration are also showing octahedral structure. Among the ligand PMBP, the C-O (C9-O1 and C11-O2) bond lengths are 1.267(3) and 1.256(3) Å, respectively, which clearly indicate that a double-bond character is exhibited between the O and C atoms (bond length of C = O is approximately 1.20 Å).In complex 1, strong intermolecular hydrogen bonds (Figure 2,Table 3) are observed between the nitrogen atom Brought to you by | New York University Bobst Library…”

“…Moreover, HPMBP has two O atoms, two N atoms, and two phenyl rings, and its hydrogen bonds network and other weak interactions can be formed (Cheng et al, 2014). The Cd(II) atom, as a IIB group metal ion, has a 4d 10 electron configuration and displays flexible coordination numbers (Sun et al, 2005;Hu and Li, 2010;Nie et al, 2010;Calatayud et al, 2013;Sharif and Najafi, 2013). In addition, some Cd(II) complexes show good fluorescent (Nie et al, 2010;Pathak et al, 2012;Calatayud et al, 2013) and antimicrobial (Zaky et al, 2012) properties.…”
