Two imidazolyl derived complexes [N,N′-butylenebis(imidazole): (fumaric acid)2 (1), and N,N′-butylenebis(imidazole): (2,4,6-trinitrophenol)2 (2)] were prepared and structurally characterized by X-ray crystallography. Compound 1 crystallizes in the triclinic, space group P-1, with a = 5.9990(12) A, b = 8.1772(16) A, c = 10.419(2) A, α = 86.88(2)°, β = 84.73(3)°, γ = 77.03(4)°, V = 495.67(17) A3, Z = 1. For 1, two dimensional network structure is formed through imidazolium moieties forming hydrogen bonds to di-ionic carboxylate groups of fumarate chains. In the same network layers and adjacent layers, C-H???O contact also accompanies the N+-H???O- hydrogen bonds, all these lead the extended architecture to show a three-dimensional lamellar structure. Compound 2 crystallizes in the triclinic, space group P - 1, with a = 7.0236(14) A, b = 8.2831(17) A, c = 12.053(2) A, α = 106.05(4)°, β = 99.13(2)°, γ = 98.84(3)°, V = 650.8(2) A3, Z = 1. In 2, two parallel imidazolium cations and two antiparallel 2,4,6-trinitrophenolate anions formed 32-membered rings through hydrogen bonding interaction, these rings extended along the c axis direction to form one dimensional railway structure. Adjacent parallel railways connect further through C-H???O hydrogen bonds between the 2-CH of the imidazole ring and the NO2 group O atoms. These weak interactions combined, the complex showed 3D layer structure.
