Abstract

The crystals of N-allylisoquinolinium chlorides of the compositions [C9H7N(C3H5)]2CuIICl4 (I), [C9H7N(C3H5)]CuICl2 · H2O (II), and [C9H7N(C3H5)]CuICl1.43Br0.57 · H2O (III) were prepared by alternating-current electrosynthesis. X-ray diffraction analysis (using diffractometer models DARCH1 for I, STOE for II, and KUMA/CCD for III, MoKα radiation) showed that the crystals of I are monoclinic, space group P21/n, a = 14.91(1) Å, b = 10.41(1) Å, c = 16.90(1) Å, γ = 109.73(8)°, V = 2470(8) Å3, Z = 4. The crystals of isostructural compounds II and III are triclinic, space group Pī, Z = 2; crystals II: a = 7.2446(6) Å, b = 7.4379(6) Å, c = 12.110(1) Å, α = 80.95(1)°, β = 85.55(1)°, γ = 86.60(1)°, V = 641.8(2) Å3; crystals III: a = 7.253(2) Å, b = 7.459(4) Å, c = 12.151(5) Å, α = 80.82(4)°, β = 83.73(3)°, γ = 86.81(4)°, V = 644.6(9) Å3. The structure of I is composed of CuIICl42– tetrahedra and N-allylisoquinolinium cations united by C–H···Cl hydrogen bonds in corrugated layers. The crystal structures of π-complexesII and III are built of [C9H7(C3H5)]2Cu2IX4 dimers, which form layers along the c axis due to the C–H···X hydrogen bonds. An important role in the structure formation is played by water molecules, which crosslink the organometallic layers to form a three-dimensional framework through the O–H···X contacts.
