The metal-free condensation of bis(2-formylphenyl) telluride (1) with a series of diamines affords macrocyclic tellurium ligands 2–7. Crystals of the protonated macrocycle 8 are monoclinic, space group P2/n with α = 10.890 (5), b = 7.414 (4), c = 24.334 (13) Å, Z = 2. The reaction of tellurium containing macrocyclic Schiff base 2 with Pd(C₆H₅CN)₂Cl₂ gives the expected 1:1 product [Pd(II)₂]Cl₂ (9). Complex 9 was treated with excess of NH₄PF₆ in methanol to give the analogous PF^-₆ salt [Pd(II)2] (PF₆)₂(10). The crystals of 10 are monoclinic, space group P2₁/n, a = 8.2250 (10), b = 21.280 (4), c = 21.150 (4), Z = 4. However, the reaction of 2 with Pt(COD)Cl₂ proceeds via novel transmetallation to yield an organoplatinum complex (11). The crystals of 11 are also monoclinic, space group P2₁/n, a = 12.3253 (14), b = 14.6557 (14), C = 13.4054 (11), Z = 4. The octahedral Ni(II) complex 12 was prepared by the reaction of NiCl₂.6H₂O with 2 and NH₄PF₆ under an inert atmosphere. For 12: triclinic, space group P1; Z = 2; a = 10.800 (8), b = 13.468 (9), c = 13.918 (11), α = 89.67 (6)°, β = 101.53(7)°, γ = 81.49 (3)°,  and V = 1961(3). Cyclic voltammetry of 12 in MeCN solution shows a well-behaved quasi-reversible (ΔE = 100 mV) Ni(III) ↔ Ni(II) couple.
