Abstract

The coordination compound [ZnCl2(Phtz)2] has been synthesized by the reaction of ZnCl2 with phthalazine (Phtz, L, C8H6N2) in an ethanol solution. Its crystal structure has been determined: crystals are triclinic, space group P 0000000, a = 7.346(1) Å, b = 8.095(1) Å, c = 14.275(1) Å, α = 85.63(1)°, β = 75.75(1)°, γ = 88.43(1)°, V = 820.4(2) Å3, ρcalc = 1.605 g/cm3, Z = 2. The zinc atom is tetrahedrally coordinated to two crystallographically nonequivalent chlorine atoms and two nitrogen atoms of the ligands L (Zn(1)–N(1), 2.036(4) Å; Zn(1)–N(3), 2.043(4) Å; Zn(1)–Cl(1), 2.225(2) Å; Zn(1)–Cl(2), 2.220(2) Å; angles NZnN, 106.1(2)°; ClZnCl, 116.47(7)°). The complexes are combined into a 1D supramolecular structure by nonclassical hydrogen bonds C–H···Cl and π–π-stacking interaction between centrosymmetric pairs of aromatic rings of one of the independent ligands. The compounds [CdI2(Phtz)] and [HgBr2(Phtz)] have also been synthesized, and their luminescent properties have been studied.
