Details of the inter­actions between centrosymmetically related pairs of unit A and unit B molecules, which result in the columns presented in Fig. 2[link]. (a) The dimer formed by two unit A molecules; single broken lines represent the π–π bonds responsible for the inter­action and the double broken lines represent the Cu1⋯Cu1(−x + 2, −y + 1, −z + 2) short contact. (b) The dimer formed by two unit B molecules, with semicoordinative inter­actions shown by broken lines. [Symmetry codes: (i) −x + 2, −y + 1, −z + 2; (ii) −x + 1, −y, −z + 1.]
