Abstract
A new tetrachlorocobalt(II) salt, [QlH]2[CoCl4]·2H2O(1) ([QlH]+ = quinolinium), has been prepared and characterized by elemental analysis, IR, UV-Vis, ESI-MS, single-crystal X-ray diffraction, and magnetic susceptibility. Compound 1 crystallizes in the monoclinic space group C2/c with cell dimensions a = 11.848(2) Å, b = 10.069(1) Å, c = 18.494(2) Å, β = 101.35(1) Å, V = 2163.3(4) Å3, Z = 4. The unit cell contains two [QlH]+ cations, one [CoCl4]2– anion and two water molecules. The [QlH]+ cations stack and form a 1D column through p···π and π···π interactions. The water molecules are linked to the anions through O-H···Cl hydrogen bonds to form two-dimensional molecular networks. The cations and [CoCl4]2– anions are linked through N-H···O and C-H···O hydrogen bonds and give further rise to a 3D hydrogen-bonding network structure. Magnetic susceptibility measurement in the temperature range 2–300 K shows that 1 exhibits a weak antiferromagnetic coupling behavior with θ = –2.90 K.
