Copper(II) complexes with bis(4-iodo-3,5-dimethylpyrazol-1-yl)methane: Synthesis, spectroscopic study, and crystal structure

X-ray crystallographic insights into post-synthetic metalation products in a metal–organic framework

“…The presence of two coordinated nitrate anions and coordinated solvent distinguishes 1·Cu from the other members of the series. However, we note that a similar Cu 2+ coordination environment was reported by Lider et al [25] from the reaction of bis(4-iodo-3,5-dimethyl-pyrazolyl)methane (bidmp) with copper(II) nitrate. Although the relative position of the solvent and nitrate anions differs between the two materials, this and other similar discrete metal complex structures [26][27][28] confirm the MOF-bound copper complex to be in a coordination environment typical for Cu(II).…”

“…The coordination environment observed in 1•Cu diverges from the tetra-aqua complexes described above. As expected for a d 9 complex, 1•Cu displays significant Jahn-Teller distortion, resulting in a distorted tetragonal pyramidal coordination environment with an equatorial [25] from the reaction of bis(4-iodo-3,5-dimethyl-pyrazolyl)methane (bidmp) with copper(II) nitrate. Although the relative position of the solvent and nitrate anions differs between the two materials, this and other similar discrete metal complex structures [26][27][28] confirm the MOF-bound copper complex to be in a coordination environment typical for Cu(II).…”
