Bis(nitrato-κO)(1,4,8,11-tetra­aza­cyclo­tetra­decane-κ4N)zinc(II) methanol monosolvate

The two ZnII atoms in the crystal structure of the title complex, [Zn(NO3)2(C10H24N4)]·CH3OH, have a distorted octa­hedral coordination sphere, defined by 1,4,8,11-tetra­aza­cyclo­tetra­decane (cyclam) N atoms in the equatorial plane and nitrate O atoms in the axial sites. The conformation of the cyclam is trans-III (R, R, S, S), which is typical for metal–cyclam complexes. Nitrate anions are involved in intra- and inter­molecular hydrogen bonding with the N–H groups of the ZnII–cyclam unit. Together with the methanol solvent mol­ecule, the hydrogen-bonding network connects the ZnII–cyclam units into ribbons running parallel to the a axis. Unlabelled Image
