Unsealed ultrasound-assisted synthesis of cadmium and lead iodide intercalation compounds

The ultrasonic effect on the interaction and phase composition of compounds of cadmium and lead iodides with organic cyclic amines such as pyridine (p y), piperidine (pp), and aniline tan) was studied. The samples were charact erized by thermal and X-ray powder diffraction analyses; their NQR and IR s pectra were recorded. Novel, ultimately, intercalated phases were prepared: PbI(2)pp(8.3+/-0.2), CdI(2)py(4.3+/-0.2), and CdI(2)py(6.0+/-0.2). The ult rasonic treatment significantly shortened the equilibration time in the sys tems in question. Complex formation proved to be more profitable in terms o f energy for the CdI2-py, CdI2-an, and CdI2-pp systems.
