[Na(DB18‐C‐6) (H 2 O) 2 ] [Na(DB18‐C‐6) (SCN) 2 ]: Two‐Dimensional Network Complex Assembled by τ‐τ Stacking Interactions, Hydrogen Bonds and Electrostatic Interactions

A novel two‐dimensional network dibenzo‐18‐crown‐6 (DB18‐C6) complex: [Na (DB18‐C‐6) (H 2 O) 2 ] [Na (DB18‐C‐6) (SCN) 2 ] has been isolated and characterized by elemental, IR and X‐ray diffraction analysis. The crystal structure belongs to monoclinic, space group P 2 1 /c with cell dimensions a = 1.06178(7), b = 1.40243(8), c = 3.03496(19) nm, β = 90.4220(10)°, V = 4.5292(5) nm 3 , Z=4, D calcd =1.351 g/ cm 3 , F (000) = 1936, R 1 = 0.0369, wR 2 = 0.0821. The most interesting feature in this structure is that complex cation and complex anion form a two‐dimensional network via τ‐τ stacking interactions, hydrogen bonds and electrostatic interactions.
