Аннотация

Hybrid compound 1-(2-fluro-4-bromobenzyl)-4-dimethylaminopyridium bis(maleonitriledithiolate)cuprate(II) [2F4BrBzDMAP]2[Cu(mnt)2] is prepared and characterized by X-ray diffraction. The compound crystallizes in the triclinic system with the space group P -1. The unit cell dimensions are a = 8.9813(11), b = 9.0794(12), c = 13.1082(17) Å and a = 88.179(2)°, b = 81.397(2)°, g = 70.736(1)° with Z = 1. The structure consists of two [2F4BrBzDMAP]+ cations and one [Cu(mnt)2]2- anion. The cations of the title compound stack into a one-dimensional column through p⋯p and p⋯p interactions, and the anions (A) and cations (C) are arranged alternatively into one 1D column in an ⋯A-CC-A-CC-A⋯ sequence through C-H⋯N hydrogen bonds and S⋯N interactions. The presence of functional groups is confirmed by the FT-IR spectrum, and optical absorption is ascertained by the recorded UV-Visible spectrum. The thermal stability of the compound is determined by thermogravimetric and differential thermal analyses. The variable-temperature magnetic susceptibility measurement shows that the compound exhibits a weak ferromagnetic coupling behavior when the temperature is lowered.
