Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Cupric bromide, is researched, Molecular Br2Cu, CAS is 7789-45-9, about A new square pyramidal copper(II) complex [Cu(C10H24N4)Br]Br: Crystal structure, thermal analysis, Hirschfeld surfaces, electrical and semiconducting properties.COA of Formula: Br2Cu.
A new organic-inorganic Cu(II) bromide complex material [Cu(C10H24N4)Br]Br was synthesized by hydrothermal method. Blue-violet crystals were characterized by x-ray single crystal diffraction, crystallizing in the orthorhombic system, noncentrosym. space group P212121, with the following unit-cell parameters: a 8.3536(1) Å, b 12.7161(3) Å, c 14.1982(3) Å. The Cu(II) sites adopt a square pyramidal distorted geometry. The crystal structure first reveals a 1-dimensional (1D) network along the a axis based on N-H···Br interactions. The dimensionality is further increased to (3D) by C-H···Br weak interactions. Hirshfeld surfaces anal. was used to study the intermol. interactions in the crystal lattices. It was then found that X-H···Br (X = N or C) contacts play an important role within the at. architecture. Besides, the phase transitions, elec. and optical properties of [Cu(C10H24N4)Br]Br were investigated and revealed a phase transition at T = 343 K. The temperature dependence of the elec. conductivity confirmed the phase transition that was also well detected with DSC. The calculated activation energies of the conduction process for the two phases are EaI = 0.30 eV, and EaII = 0.69 eV.
