The solvothermal reaction of CuCl with R-(-)-1-allyl-3-methylpiperazine at 70 ℃ gives one-dimensional chain Cu-coordination polymer through olefin moiety binding to Cu atoms formulated as Cu(C8H16N2)Cl. It is interesting to note that through Cu2Cl2 dimer unit 1 results in a supramolecular 3-dimensional coordination polymer. Powdered sample measurement of 1 reveals that 1 is second-harmonic generation (SHG) active compound. Crystal parameters for 1, space group P212121, a=0.763 1(9) nm, b=0.891 0(10) nm, c=1.494 6(17) nm, α=90°, β=90°, γ=90°, V=1.016(2) nm3, Z=2, M=478.44, Dc=1.564 Mg·m-3. CCDC: 650193.
The crystal structure of [Bi2Cl10(H2-Norf)4(H2O)8] (1) comprises + cations and 4- anions, that are loosely associated via H-bonding interactions, as well as water molecules that also participate in H-bonding interactions. Strong blue-fluorescent emission of 1 at solid state is observed at the room temperature. CCDC: 238237.
The hydrothermal reaction of Zn(NO3)2, NaN3, and 1-(4-pyridyl)-2-(2-cyanobenzene) ethylene (PCE), at the mole ratio 1∶2∶2 in methanol and water at 70 ℃ for two days afforded [Zn(PCE)2(N3)2], the structure of which features a four-coordinated distorted tetrahedron geometry around zinc(Ⅱ). CCDC: 235945.
The hydrothermal treatment of Cu(ClO4)2·6H2O and Norfloxacin (H-Norf) afforded [Cu(H-Norf)2(ClO4)2] (1) in which center Cu has a square planar geometry while perchlorate just acts as charge balance anions. CCDC: 140821.
