The nickel(II) and zinc(II) complexes of 6-ethyldibenzo[b,i]-1,4,8,11-tetraazacyclotetradeca-4,6-diene were synthesized and their crystal structures were determined by single-crystal X-ray diffractometry. The crystal system of NiLCl is monoclinic with the space group of P21/c and Z = 4. The unit cell dimensions are a = 8.452(2)Å, b = 12.781(3)Å and c = 17.893(3)Å with β = 98.38(2)°, V = 1912.2(7)Å3. The crystal system of ZnLCl is monoclinic with the space group of C2/c and Z = 8. The unit cell dimensions are a = 24.860(3)Å, b = 11.209(2)Å and c = 18.252(2)Å with β = 116.959(7)°, V = 4533.4(9)Å3. The nickel(II) ion of NiLCl is coordinated through four nitrogen atoms to form a square-planar geometry and the zinc(II) ion has a square-pyramid geometry with four nitrogen atoms in a plane and one chloride atom at an axial position.
