Abstract: | The bimetallic title complex, CuFe(CN)5(C12H30N6O2)(NO)] or Cu(L)Fe(CN)5(NO)] where L is 1,8‐bis(2‐hydroxyethyl)‐1,3,6,8,10,13‐hexaazacyclotetradecane], has a one‐dimensional zigzag polymeric –Cu(L)–NC–Fe(NO)(CN)3–CN–Cu(L)– chain, in which the CuII and FeII centres are linked by two CN groups. In the complex, the CuII ion is coordinated by four N atoms from the L ligand Cu—N(L) = 1.999 (2)–2.016 (2) Å] and two cyanide N atoms Cu—N = 2.383 (2) and 2.902 (3) Å], and has an elongated octahedral geometry. The FeII centre is in a distorted octahedral environment, with Fe—N(nitroso) = 1.656 (2) Å and Fe—C(CN) = 1.938 (3)–1.948 (3) Å. The one‐dimensional zigzag chains are linked to form a three‐dimensional network via N—H⋯N and O—H⋯N hydrogen bonds. |
