| dc.description.abstractEn | A new organic-inorganic Cu(II) bromide complex material [Cu(C10H24N4)Br]Br has been synthesized by hydrothermal method. Blue-violet crystals are characterized by X‐ray single crystal diffraction, crystallizing in the orthorhombic system, non-centrosymmetric space group P212121, with the following unit-cell parameters: a = 8.3536 (1) Å, b = 12.7161 (3) Å, c = 14.1982 (3) Å, V = 1508.21 (5) Å3. This study shows that the Cu(II) sites adopt a square pyramidal distorted geometry. The crystal structure first reveals a one-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 analysis was used to study the intermolecular interactions in the crystal lattices. It was then found that X-H···Br (X = N or C) contacts play an important role within the atomic architecture. Besides, the phase transitions, electric and optical properties of [Cu(C10H24N4)Br]Br were investigated and revealed a phase transition at T = 343 K. The temperature dependence of the electrical conductivity confirmed the phase transition that was also well detected with differential scanning calorimetry. The calculated activation energies of the conduction process for the two phases are EaI=0.30 eV, and EaII=0.69 eV. | |
