| The planar, dinuclear, tridentate ligands, 1,3,5,7-tetrakis(2-pyridylimino)benzodipyrrole (TAII) and 1,3,5,7-tetrakis(4,6-dimethyl-2-pyridylimino)benzodipyrrole (DiMeTAII) were synthesized and characterized as were all intermediates characterized by both infrared and {dollar}sp1{dollar}H-NMR spectra. Evidence is presented for the formation of {dollar}rm Mosb4(OAc)sb6{dollar}-(DiMeTAII) (I), the dinuclear analog of {dollar}rm Mo2(OAc)sb3{dollar}-BAII using UV/Vis to show the {dollar}deltatodeltasp*{dollar} transition typical of the quadruple bond and for the determination of percent molybdenum which is consistent with the proposed structure. A review of recent studies into the field of quadruply bonded metal containing polymers will be discussed along with application of compound (I) in this field. |
