The crystal structure of a Ni(II) complex with 1,7‐diaminoethyl‐4,10‐dimethyl,4,7,10‐tetraazacyclododecane has been determined by X‐ray diffraction method. Crystal data for NiC 14 H 36 Br 2 N 6 O: monoclinic, space group P2 1 /n, a=0.8848(3), b=1.4656(3), c=1.5828(3) nm, β=90.47(3)°, V=2.0525 nm 3 , Z=4. The two pendant primary amino groups are located in cis positions in the complex, their nitrogen atoms and the four nitrogen donors of the fold tetraaza‐macrocycle coordinate Ni(II) ion, forming a distorted octahedral geometry.
