Abstract:

Compounds of macrocyclic ligand 4,11-dihydro-dibenzo b, i1,4,8,11tetraaza14annulene, dB-TAA, have been prepared with Cu2, Ni2, Pd2, Pt2. The palladium complex crystallizes in three crystalline modifications, two of which are similar to the structurally characterized compound NidB-TAA, while the third form packs as cofacial dimers in the solid state. Partial oxidation of PddB-TAA and PtdB-TAA yields the mixed valence nonstoichiometric compounds PddB-TAAI2.0 sigma 0.4 ohm to the minus 1 power centimeter to the minus 1, delta E 0.04-0.06 eV, PtdB-TAAI1.35 sigma 0.12 ohm to the minus 1 power centimeter, to the minus 1 power, delta E 0.06-0.12 eV, and PtdB-TAAI1.50 sigma 0.03 ohm to the minus 1 power centimeter to the minus 1 power.
