In the metal-hybrids of L(1), a reaction with HgCl(2) 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 HgI(2) gave open-frame network structures without any solvent of crystallization from both dmso and dmf (1c). However, reaction with HgBr(2) 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 HgCl(2) and HgI(2), 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 (1) over bar space groups 1a: a = 9.049(2), b = 13.646(4), c = 16.298(4) angstrom, a = 111.99(1), beta = 90.43(1), gamma = 101.57(1)degrees, Z = 2, V = 1820.6(8) angstrom(3), 1b: a = 8.9799(3), b = 13.611(5), c = 16.355(5) angstrom, a = 111.57(1), beta = 92.37(1), gamma = 101.07(1)degrees, Z = 2, V = 1810.05(11) angstrom(3) complexes 1c-1f crystallize into monoclinic space groups [1c: C2/c, a = 27.661(7), b = 18.821(4), c = 15.786(4) angstrom, beta = 113.13(1), Z = 4, V = 7558(3) angstrom(3), 1d: P2(1)/c, a = 17.950(5), b = 9.031(2), c = 22.200(6) angstrom, beta = 113.62(1), Z = 4, V = 3297.3(15) angstrom(3), 1e: C2/c, a = 26.753(15), b = 18.415(10), c = 14.940(7) angstrom, beta = 109.50(1), Z = 4, V = 6938(6) angstrom(3), 1f: P2(1)/n, a = 17.697(10), b = 9.224(5), c = 21.933(12) angstrom, beta = 112.50(1), Z = 4, V = 3308(3) angstrom(3)].
