Abstract

Rare examples of homodinuclear zwitterionic Pd(II) and Pt(II) complexes with bridging, two-coordinate P{cyclo-CH(2)N(R)CHN(R)CH(2)} ligands (R = 4-FC(6)H(4)CH(2), C(6)H(5)CH(2)) 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.
