Description: Copper(I) chloride, iodide, and bromide were reacted with aliphatic diamine ligands (L) piperazine (Pip), N-methylpiperazine (MePip), N,N'-dimethylpiperazine (Me2Pip), N-ethylpiperazine (EtPip), N,N'-diethylpiperazine (Et2Pip), 1,4-diazabicyclo[2.2.2]octane (DABCO), and hexamethylenetetramine (HMTA) via open solvent reflux. Parallel reactions were performed under solventothermal conditions. Reflux reactions produced complexes (CuI)2L for L = Pip, MePip, Me2Pip, EtPip, Et2Pip, HMTA and (CuI)4L for L = HMTA. Reflux reactions also produced (CuBr)2L for L = Pip, Me2Pip, EtPip, Et2Pip, DABCO, HMTA and (CuBr)4L for L = HMTA. Also produced were [Cu2Cl4](H2Pip), a second phase [Cu2Cl4](H2Pip), [Cu3Cl5](H2MePip), [Cu4Cl6](H2Me2Pip), (CuI)4(DABCO)2, and (CuBr)4(MePip)2. X-ray structures are presented for [Cu2Cl4](H2Pip), a second phase [Cu2Cl4](H2Pip), [Cu3Cl5](H2MePip), [Cu4Cl6](H2Me2Pip), (CuI)2(Pip), (CuI)2(Et2Pip), (CuI)2(Et2Pip), (CuI)4(DABCO)2, (CuBr)4(MePip)2, and (CuBr)2(Me2Pip). These structures show certain trends including cubane node formations, Cu���Cu interactions at less than van der Waals distances, and microporous structure. Luminescence behavior was recorded for reflux products. Networks with CuI, particularly (CuI)2(Me2Pip), (CuI)2(Et2Pip) and (CuI)4(DABCO)2, showed strong luminescence.
