AbstractSynthesis and solid‐state structure elucidation of metal–organic hybrids of 1,3,5‐tris(4‐pyridylsulfanylmethyl)‐2,4,6‐trimethylbenzene with HgII halides (HgCl2, HgBr2, and HgI2) are reported. In the metal‐hybrids of L1, a reaction with HgCl2 in dmso as well as in dmf gave host–guest complexes, 1a and 1b, respectively, with the corresponding solvent of crystallization as the guests, while a reaction with HgI2 gave open‐frame network structures without any solvent of crystallization from both dmso and dmf (1c). However, reaction with HgBr2 gave crystals of two different morphologies from each solvent dmso and dmf (1d–1f), which corresponds to the structures with and without solvent of crystallization that resemble the related structures formed by HgCl2 and HgI2, respectively. Three‐dimensional structures of all the compounds were characterized by single‐crystal X‐ray diffraction methods. While 1a and 1b crystallize in triclinic P$\bar 1}$ space groups 1a: a = 9.049(2), b = 13.646(4), c = 16.298(4) Å, α = 111.99(1), β = 90.43(1), γ = 101.57(1)°, Z = 2, V = 1820.6(8) Å3; 1b: a = 8.979(3), b = 13.611(5), c = 16.355(5) Å, α = 111.57(1), β = 92.37(1), γ = 101.07(1)°, Z = 2, V = 1810.05(11) Å3, complexes 1c–1f crystallize into monoclinic space groups [1c: C2/c, a = 27.661(7), b = 18.821(4), c = 15.786(4) Å, β = 113.13(1), Z = 4, V = 7558(3) Å3, 1d: P21/c, a = 17.950(5), b = 9.031(2), c = 22.200(6) Å, β = 113.62(1), Z = 4, V = 3297.3(15) Å3, 1e: C2/c, a = 26.753(15), b = 18.415(10), c = 14.940(7) Å, β = 109.50(1), Z = 4, V = 6938(6) Å3, 1f: P21/n, a = 17.697(10), b = 9.224(5), c = 21.933(12) Å, β = 112.50(1), Z = 4, V = 3308(3) Å3].
