Host layer buckling in the compounds formed by exfoliation and restacking of cadmium phosphorus trisulphide with adenosine monophosphate included

Exfoliated single layer cadmium phosphorus trisulphide has been combined with the biological molecule adenosine monophosphate (AMP) to form the novel restacked compound LixCd0.8PS3(AMP)z(H2O)y. Composition was determined using energy dispersive X-ray spectroscopy, and the structure of these compounds was studied using X-ray diffraction on oriented films. 0–80% relative humidity range, for (AMP)0.5, a host plane spacing near 19.6 Å was found. Electron density calculations based on the X-ray diffraction pattern suggest a model for the arrangement of guest AMP molecules between the host layers, with an accompanying water molecule. The calculations also suggest that there is a buckling in the host layer of about ± 0.6  Å.
