Bis(18-crown-6)-1⁶O,3⁶O-bis(-1,1-dicyanoethylene-2,2-dithiolato)-1:2³N:S,S';2:3³S,S':N-dipotassium(I)copper(II) 1,2-dichloroethane solvate

Abstract: In the title complex, [CuK₂(C₄N₂S₂)₂(C₁₂H₂₄O₆)₂]·C₂H₄Cl₂, the Cu^II atom lies on an inversion centre and the 1,2-dichloroethane solvate lies on another inversion centre. The asymmetric unit therefore comprises one [K(18-crown-6)]⁺ complex cation, one-half of the [Cu(i-mnt)₂]^2- anion (i-mnt is 1,1-dicyanoethylene-2,2-dithiolate) and one-half of the dichloroethane solvent molecule. Each K^I ion binds to the six ether O atoms and N atoms from two i-mnt^2- ligands. The Cu atoms adopt a distorted square-planar coordination geometry. K-N bonds from each of the four cyano groups link the cations and anions into planar sheets along the diagonal of the ac plane and these sheets pack in layers in the bc plane.
