摘要:
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 Cu-II and Fe-II centres are linked by two CN groups. In the complex, the Cu-II ion is coordinated by four N atoms from the L ligand [Cu - N( L) = 1.999 (2) - 2.016 (2) Angstrom] and two cyanide N atoms [Cu - N = 2.383 (2) and 2.902 (3) Angstrom], and has an elongated octahedral geometry. The Fe-II centre is in a distorted octahedral environment, with Fe - N(nitroso) = 1.656 (2) Angstrom and Fe - C(CN) = 1.938 (3) - 1.948 (3) Angstrom. The one-dimensional zigzag chains are linked to form a three-dimensional network via N - H..circleN and O-H ...N hydrogen bonds.
