C 27 H 20 ClCuN 5 O 4 ,triclinic, P1 (no. 2), a =7.6112(3) Å, b =9.5277(5) Å, c =17.2876(7) Å, a =86.815( Source of material Am ixture of 3,6-bis((pyridin-2-yl)methoxy)benzene-1,2dinitrile (1.368 g, 4m mol), CuCl 2. · . 2H 2 O( 0.17 g, 1m mol), npentanol (25 mL), DBU (1.5 mL) was refluxed for 10 hours, cooled to room temperature and filtered off. The filter residue was washed with methanol and recrystallized from dichloromethane to give apale yellow solid of L(yield 9%).

Crystals of the title compound were obtained by dissolving L( 0.05 g, 0.1 mmol) and CuCl 2. · . 2H 2 O( 0.017 . g, 0.1 . mmol) in amixture of methanol and dichloromethane (1:1), followed by slow evaporation of the solvents. Yellow blockshaped crystals were collected (yield 25 %). Experimental details All Hatoms on Cand Oatoms were generated geometrically and refined as riding atoms with d(C-H) =0.93 -0.97 Å, d(O-H) = 0.82 Å,and U iso (H) =1.5 U iso (C,O) for methanol and U iso (H) = 1.2 U eq (C) for other Hatoms bonded to Catoms.
