Synthesis, Crystal Structure Analysis and Characterization of Mercury(ii) Complex Containing 2-(Aminomethyl)pyridine and Bromide

Abstract

The new complex of [Hg(2-AMPy) 2 Br] 2 .HgBr 4 (1) was synthesized from the reaction of HgBr 2 with 2-(aminomethyl)pyridine (2-AMPy) in methanolic solution. Suitable crystals of 1 for diffraction experiment was obtained by slow evaporation from DMSO. Resulted complex was characterized by IR, elemental analysis, thermal analysis and single crystal X-ray diffraction. In this compound, two five-coordinated mercury centers in the cationic parts have slightly and highly distorted square-based pyramidal geometries by the trigonal-indexes, τ 5 , of 0.18 and 0.49, respectively. According to four-coordinate geometry index, τ4, of 0.95, anionic part has perfect tetrahedral geometry.

“…In addition, it was expected to show high introduction capability in the GMA with an epoxy group-grafted MNWF because it has an amino group [ 37 ]. The method of introducing functional groups was determined based on research data on the bonding of metal ions with 4-AMP or 2-picolylamine, similar to 4-AMP’s molecular structure [ 33 , 34 , 38 , 39 ]. The process of selecting 4-AMP using the results of the CCDC database is shown in Figure 4 .…”
