Aqueous reactions of copper(I) cyanide with 1-phenylpiperazine (PhPip) in the presence of KCN produce network compounds having CuCN:PhPip stoichiometries of 1:1, 3:2, and 4:1 depending on the mixing ratio used. In addition to these phases, hydrothermal synthesis yields a 5:3 network. Crystal structures of these four compounds are reported herein. The (CuCN)(PhPip) network (1) forms sheets consisting of Cu centers that coordinate all PhPip via NH only, and are linked together by μ3-cyano bridges. The (CuCN) 3(PhPip)2 network (2) exists as a series of dual-chain ladders. All Cu centers are 3-coordinate and half of the PhPip ligands bridge pairs of chains using both NH and NPh, while the other PhPip are only NH bound. The (CuCN)5(PhPip)3 network (3) forms three independent sets of 1D chains: 2[(CuCN)(PhPip)] ·(CuCN)3(PhPip). Both 2- and 3-coordinate copper atoms are present and all PhPip ligands bond only through NH. The (CuCN) 4(PhPip) network (4) forms identical, but orthogonal, interpenetrating sheets consisting of 2- and 3-coordinate CuCN chains linked by bridging PhPip ligands. Pairwise cuprophilic interactions are seen in the 5:3 and 4:1 networks. The 3:2 compound shows visible photoluminescence associated with Cu-CN MLCT. Compound 1 crystallizes in the monoclinic P21/c space group with cell parameters: a = 17.6123(3) A, b = 6.89480(10) A, c = 8.6154(2) A, β = 96.1460(10), V = 1040.18(3) A3, and Z = 4. Compound 2 crystallizes in the triclinic P - 1 space group with cell parameters: a = 9.93710(10) A, b = 10.6359(2) A, c = 12.1230(2) A, α = 105.7110(10), β = 100.6110(10), γ = 97.7230(10), V = 1189.11(3) A3, and Z = 2. Compound 3 crystallizes in the monoclinic P21/n space group with cell parameters: a = 15.9018(2) A, b = 9.38850(10) A, c = 26.1864(3) A, β = 104.5110(10), V = 3784.76(8) A3, and Z = 4. Compound 4 crystallizes in the monoclinic P21 space group with cell parameters: a = 13.4773(3) A, b = 7.8460(2) A, c = 8.5527(2) A, β = 105.1820(10), V = 872.82(4) A3, and Z = 2. Graphical Abstract: The aqueous hydrothermal and non-hydrothermal reactions of copper(I) cyanide with 1-phenylpiperazine (PhPip) in the presence of KCN was studied. The structures of (CuCN)(PhPip)·(CuCN)3(PhPip) 2, (CuCN)5(PhPip)3, and (CuCN) 4(PhPip) are reported.[Figure not available: see fulltext.]

A new synthetic procedure developed recently in our laboratories has made possible the synthesis of variety of new complexes of CuCN with diamines. Synthesis was effected by adding the ligand to a solution of CuCN in aqueous sodium thiosulfate. This procedure also provides an alternative pathway to a novel diamine complex reported by us previously, (CuCN)3(HMTA)2 (1) (where HMTA = hexamethylenetetramine). The other diamine ligands used were l,4-diazabicyclo[2.2.2]octane (dabco), 1,4-dimethylpiperazine (dmpip), piperazine (pip), 1,4-butanediamine (butda), N,N,N',N,-tetramethylethylenediamine (tetmen), and N-phenylpiperazine (phpip). Complex 2, Cu2(CN)3(dabco-H), crystallizes in the hexagonal space group P63 with unit cell dimensions a = 8.174(3) ?, c = 8.083(4) A ?, and Z = 2. Complex 3, (CuCN)2(dmpip), crystallizes in the monoclinic space group C2/m with unit cell dimensions a = 8.812(3) ?, b = 9.631(2) ?, c = 7.266(3) ?, β= 113.40(3)°, and Z = 2. Complex 4, (CuCN)2(pip), crystallizes in the monoclinic space group C2/c with unit cell dimensions a = 9.439(3) ?, b = 10.561(2) ?, c = 8.870(3) ?, β= 98.32(3)°, and Z = 4. Complex 5, Cu2(CN)3(pip-H), crystallizes in the monoclinic space group C2/c with unit cell dimensions a = 20.573(9) ?, b = 8.354(2) ?, c = 15.989(6) ?, β= 133.70(3)°, and Z = 8. Complex 6, (CuCN)2(butda), crystallizes in the monoclinic space group P21/c with unit cell dimensions a = 10.456(2) ?, b = 5.550(1) A, c = 8.669(3) ?, β= 106.80(2)°, and Z = 2. Complex 7, (CuCN)2(tetmen), crystallizes in the orthorhombic space group Cmc21 with unit cell dimensions a = 11.889(4) ?, b -33.380(8) ?, c = 9.012(3) ?, and Z = 12. Complex 8, (CuCN)(phpip), crystallizes in the monoclinic space group P21/c with unit cell dimensions a = 17.8819(3) ?, b = 6.9190(1) ?, c = 8.6972(1) ?, β= 96.720(1)°, and Z = 4.
