摘要:
A new diphosphazane ligand, Ph2PN(CHMe2)P(Ph){1,3-dimethoxycalix[4]arene} (2), in which the P-N-P unit is appended to calix[4]arene backbone, and its PdCl2 complex (3) have been synthesized. The structures of the conformers of both the compounds in solution have been elucidated with the help of two-dimensional NMR experiments. Single crystal X-ray diffraction studies reveal the partial cone and cone conformations of the calixarene unit in the ligand (2) and the Pd-complex (3), respectively. (c) 2007 Elsevier Ltd.
