Under hydrothermal conditions, two novel Zn(ii)/Cd(ii) complexes [Cd2(L)4(Cl)2]·(SO4) (1) and {[Zn2(L)2(Sip)(OH)]·H2O}n (2) (L = 2-(2,6-dichlorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline, NaH2Sip = 5-sulfoisophthalic acid monosodium salt) were successfully synthesized and characterized by elemental analysis, single-crystal X-ray diffraction, and Hirshfeld surface analysis. The study reveals that complex 1 is constructed from the binuclear [Cd2L4Cl2] unit, and the [Cd2L4Cl2] units are linked via C–H⋯π and C–Cl⋯π interactions into 2D supramolecular layers. These 2D layers are further connected to generate 3D structures by N–H⋯O and N–H⋯S hydrogen bonds. Complex 2 exhibits a 1D double-chain structure consisting of a binuclear [Zn2L2(OH)] unit, which is further connected by π–π interaction to shape a 2D supramolecular structure. |
