Three copper(I) complexes [Cu(µ2-L1)I]n (1), [CuL1(µ-1,1,3-SeCN)]n (2) and [Cu2(µ2-I)2(L2)2] (3), where L1 = 5,6-diphenyl-2,3-dihydropyrazine and L2 = 2,3-dihydro-5,6-bis(4-methoxyphenyl)pyrazine, have been synthesized via in situ reduction of copper(II) precursors under ambient conditions and they have been characterized by elemental analysis, IR and UV–Vis spectroscopy and single-crystal X-ray diffraction studies. The copper(I) centres have trigonal planar geometries in complexes 1 and 3, whereas it is tetrahedral in complex 2. Complex 1 has a 1-D chain structure, complex 2 features a ladder-like polymeric coordination network with Cu2Se2 core, complex 3 features a double iodide bridge dimer. Complex 1 crystallizes in monoclinic space group P21/c whereas complexes 2 and 3 crystallize in triclinic space group P1−1. Complexes 1 and 2 show significant C-H···π interactions, but complex 3 has no such C–H⋯π interactions.
