Dichlorido(10,11,12,13-tetra-hydro-4,5,9,14-tetra-azabenzo[b]triphenyl-ene)cadmium(II) hemihydrate.

In the title compound, [CdCl(2)(C(18)H(14)N(4))(2)]·0.5H(2)O, the Cd atom assumes a distorted octa-hedral trans-CdCl(2)N(4) geometry arising from its coordination by two N,N'-bidentate 10,11,12,13-tetra-hydro-4,5,9,14-tetra-azabenzo[b]triphenyl-ene (TBBT) mol-ecules and two chloride ions. In the crystal, π-π aromatic stacking inter-actions between adjacent TTBT rings are seen, with a centroid-centroid distance of 3.604 (3) Å. An O-H⋯Cl hydrogen bond between the half-occupied water molecule and one chloride ion also occurs.
