title: Architectural spiroligomers designed for binuclear metal complex templating.
abstract: The first structurally, spectroscopically, and electronically characterized metal-spiroligomer complexes are reported. The binuclear [M2L2](4+) ions (M = Mn, Zn) are macrocyclic "squares" and are characterized by X-ray diffraction, (1)H and (13)C NMR, electronic absorption, emission, and mass spectroscopies. The manganese complex contains two spin-independent Mn(II) ions and is additionally characterized using EPR and CD spectroscopies and CV.
