Two new complexes, [Cu(L1){N(CN)2}]·ClO4 (1) (L1 is 1,8-dimethyl-1,3,6,8,10,13-hexa-azacyclotetradecane) and [Co(L2)(N3)2]·ClO4 (2) (L2 is 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetra-azacyclotetradecane) have been synthesized and characterized. The compounds crystallize in the monoclinic system P21 space group for 1 and P21/n for 2. Single crystal X-ray analysis reveals that the compound 1 assumes a one-dimensional structure via hydrogen-bonding interactions, in which each Cu(II) ion is coordinated by four nitrogen atoms from ligand L1 and one nitrogen atom from [N(CN)2]− anion. For compound 2, each Co(III) ion is coordinated by four nitrogen atoms of ligand L2 and two nitrogen atoms from N3 − anion.
