Bis(n-do-decyl-ammonium) bis-(chlor-anil-ato)di-ethano-lcuprate(II).

In the title compound, (C12H25NH3)2[Cu(C6Cl2O4)2(C2H5OH)2], the Cu(II) atom lies on a crystallographic inversion center and is coordinated in a distorted octa-hedral geometry by four O atoms of two chloranilate ligands and two O atoms of two ethanol mol-ecules which are trans to each other in the axial positions. In the crystal, the Cu(II) mononuclear dianions are linked by O-H⋯O hydrogen bonds into a tape along the a-axis direction. The tapes are linked through N-H⋯O hydrogen bonds between the dianion and the n-do-decyl-ammonium cation, forming a two-dimensional network parallel to the ab plane.
