Unusual Metal-Coordinated Zwitterionic P-C-N-C-N-C Phosphido Adducts
Rare examples of homodinuclear zwitterionic Pd-II and Pt-II complexes with bridging, two-coordinate P{cyclo-CH2N(R)CHN-(R)CH2} ligands (R = 4-FC6H4CH2, C6H5CH2) have been characterized by single-crystal X-ray diffraction using synchrotron radiation. Short N-C distances and enlarged N-C-N bond angles support electron delocalization in the central N-C-N backbone.
