Crystal structure, Hirshfeld surface, novel XPS spectroscopy and magnetic properties of a hybrid solid with tetrahedral coordination sphere tetrabromocuprate (II)

A new organic-inorganic hybrid crystal material (C18H26N2)[CuBr4] has been synthesized. This hybrid shows novel XPS spectroscopy and EPR silent behavior at room temperature. The variable-temperature magnetic susceptibility displays an isolation of CuII feature.68
