- Abstract
Two d10 M(II) (M = Cd and Zn) coordination polymers (CPs) with chemical formulas, {[Cd(L1)(NCS)2(H2O)]⋅C2H5OH}n(1), and {[Zn(L1)(NCS)2]⋅C2H5OH⋅0.5H2O}n(2) (L1 = 1,3,5‐tris(4‐pyridylsulfanylmethyl)‐2,4,6‐trimethylbenzene) were synthesized and structurally characterized by single‐crystal x‐ray diffraction method. In compound 1, the coordination environment of Cd(II) ion is distorted octahedral bonded to three nitrogen donors from three L1 ligands located in a facial‐position, two nitrogen donors from NCS− and one water molecule. The L1 acts as a bridge ligand with tris‐monodentate coordination mode in a cis‐cis‐cis structural conformation, connecting the Cd(II) to form a two‐dimensional (2D) zigzag‐like layered metal‐organic frameworks. Adjacent 2D layers are then arranged orderly in an ABAB manner to complete its three‐dimensional (3D) supramolecular architecture. In compound 2, the coordination environment of Zn(II) ion is distorted tetrahedral bonded to two nitrogen donors from two L1 ligands and two nitrogen donors from two NCS− ligands. The L1 acts as a bridge ligand with bis‐monodentate coordination mode in a cis‐cis‐cis structural conformation, connecting the Zn(II) ions to form a one‐dimensional (1D) zigzag‐like polymeric chain. Adjacent chains are arranged orderly in an alternate ABAB manner to generate a 2D framework and then further arranged in an AAA manner to complete its 3D supramolecular architecture. The structural characterization as well as thermal‐stability and solvents de‐/ad‐sorption behavior of 1 and 2 are studied and discussed in details.
