Three organic–inorganic hybrid compounds have been prepared by combination of the tripyridinium imidazole of cation [2,4,5-tri(4-pyridyl)imidazole] (L) and a series of perhalometallate anions to give, namely [H3L(CuCl4)]Cl (1), [(H3L)2(PdCl4)3]·4H2O (2) and [(H3L)2(PtCl4)3]·4H2O (3), which have been structurally characterized by single-crystal X-ray diffraction analysis, showing that the hydrogen bonding interactions of the resulting 1D, 2D, and 3D networks contain at least one of the following synthons: X–H⋯ClnM− [X = C, N, N+; n = 0,1,2; M = Cu(II), Pd(II), Pt(II)] The dimensions are enhanced further by strong X–H⋯Cl− (C, N+) and OH⋯ClnM− [n = 1,2; M = Pd(II), Pt(II)] hydrogen bonds. Additional weak C–H⋯O, π–π stacking and Cl⋯Cl interactions stabilize the crystal structures further.
