Abstract Single crystals of CuCl C6H4N3(OC3H5)(I) are synthesized by ac electrochemical method from Cu(II) chloride and 1-allyloxybenzotriazole in ethanol solution and their unit cell parameters are determined: space group P21/a a=11.583(4) , b=11.443(7) , c=8.620(4) , =108.77(3), V=1082(2) 3, R(F)=0.0366, Rw(F)=0.0396 for 1095 reflections. In the structure of p-complex I, inorganic fragment Cu2Cl2 forms centrocymmetric parallelogram. A molecule of 1-allyloxybenzotriazole acts as a bridge, which is bonded to the Cu atoms of two inorganic dimers through the C=C bond of the allyl group and to the N atom of a triazole ring. Owing to this bridging function, the ligand molecules form zigzag organometallic layers. The trigonal-pyramidal coordination sphere of a metal atom includes two Cl atoms and the C=C group. The structural motif of complex I significantly differs from that of the previously studied 2CuCl C6H4N3(OC3H5) and resembles the motif of a bromide analog Cu2Br2 [C6H4N3(OC3H5)]2.
