Abstract
Four new inorganic–organic hybrid coordination polymers {[Ag2L(NO3)2]·H2O}n (1), [Ag2L(SCN)2]n (2), [CdL(SCN)2]n (3), and [CdLI2]n (4) have been synthesized and structurally characterized by IR spectroscopy, thermogravimetric (TG) analyses and complete single crystal structure analyses, where L is 2,5-bis(pyrazinyl)-3,4-diaza-2,4-hexadiene. The structure of polymer 1 is a 3D coordination framework containing Ag-(μ-NO3−) inorganic bridging units, in which each L coordinates four silver atoms through two pyrazinylimine chelate units and two terminal monodentate pyrazinyl N donors. Polymer 2 displays a new 3D inorganic–organic hybrid network through the coordination interactions between Ag-(1,1,3-μ-SCN−) inorganic 2D sheets and bidentate bridging ligands with two terminal monodentate pyrazinyl N donors. Bidentate bridging ligands link 1D inorganic chains Cd-(1,3-μ-SCN−) system for 3 and Cd-(μ-I−) system for 4 to form a similar two-dimensional layer network. The luminescent properties of polymers 1–4 were investigated in the solid state at room temperature.
