The tetrachlorocuprate(II), tetrabromocuprate(II) and tetrakis(izothiocyanate)cuprate(II) complexes of diantipyrylmethanium cations have been prepared and formulated as (H2DAM)CuCl4, (H2DAM)CuBr4, and (HDAM)2Cu(NCS)4 on the basis of spectral data (IR, UV-VIS) and elemental analysis. The EPR spectra, variable temperature magnetic susceptibility and thermal properties in air have been investigated. The results indicate for all complexes a distored tetrahedral configuration. All studied complexes exhibited Curie-Weiss behaviour between 80-300 K. Thermal decomposition is a multistage process and yields CuO as final product.
