A 156cm–1 red-shift is gained theoretically to demonstrate the presence of non-neglectable weak H-bonds and result in the discovery of the rarely reported trimeric H-bond, which consists of three independent hydroxyl donors and only one Cl– acceptor, in the field of crystal materials. We explained the relative weakness of this kind of hydrogen bond which may have a critical effect on the lattice symmetry and magnetic structure.
