Structure and solution dynamics of a “P-N-P” ligand attached to calix[4]arene scaffold and its palladium dichloride complex

Synthesis, solid-state structure analysis and solution NMR study of a new calixarene-phosphorus ligand, Ph2PN(CHMe2)P(Ph){1,3-dimethoxycalix[4]arene} (2), incorporating a “P-N-P” unit and its PdCl2 complex (3), are reported.
