General procedure: The solution of CuX2 salt (0.5 mmol, 120.8 mg of Cu(NO3)23H2Ofor 3a/b and 180.8 mg of Cu(CF3SO3)2 for 4) in 5.0 mL of ethanol (3aand 4) or methanol (3b) was mixed with the solution of anequimolar amount of 1,7-phen (90.1 mg) in 5.0 mL of ethanol (3aand 4) or methanol (3b). After addition of 1,7-phen, a solutionchanged color from blue to green, and no formation of metalliccopper was observed. The reaction mixture was stirred at roomtemperature for 3-4 h and then left at room temperature to slowlyevaporate. Crystals of compounds 3a/b were obtained from themother solution, while those of compound 4 were obtained after recrystallization of the solid product formed from the reactionmixture in 15.0 mL of acetonitrile. These crystals were filtered offand dried at ambient temperature. Yield (calculated on the basisof 1,7-phen): 65.7 mg (54%) for 3a, 74.2 mg (61%) for 3b and94.1 mg (57%) for 4.

General procedure: To a 50 mL Schlenk flask, 200 mg (0.35 mmol) H4L2, 310 mg(0.86 mmol) of Cu(OTf)2, and 20 mL of dry CH3CN were added and theresulting mixture allowed to stir for 10 min. To the suspension, 1.0 mLof a 2.18M solution of NMe4OH in MeOH was added, resulting in acolor change to a deep green. After stirring for 1 h, solvent was removedunder vacuum to bring the volume to?5 mL. Diethyl ether (20 mL)was added, resulting in the precipitation of green powder that wascollected by filtration, washed with Et2O (2 x 20 mL) and allowed to dry(96 mg, 33%). Crystals were obtained by addition of KOTf to the CH3CNsolution. Repeated attempts to obtain accurate and reproducible CHNanalysis for K(THF)[L2Cu2(CH3CONH)] and the following complexeswere unsuccessful, which we attribute to incomplete combustion.
