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.
[Ni3O(TBPLA)(H2O)](ClO4)4(H2O)6 [TBPLA=(S)-1,1',1''-2,4,6-trimethylbenzene-1,3,5-triyl)-tris(methylene)-tris-(pyrrolidine-2-carboxylate)] was found to possibly display multiferroic property (the coexistence of ferroelectricity and ferromagnetism). The magnetic property of this compound was studied and no magnetic hysteresis loop was found probably due to an intrinsic fluctuation for the magnetic exchange energy.
The solvothermal reaction (D2O) of 2,6-dideuterium-4-cyanopyridine with ZnCl2 in the presence of NaN3 offers a novel complex Zn(OD)(C6H2D2N4) (1) in which Zn has a distorted tetrahedron composed of two N atoms from one tetrazoyl group and pyridyl group and two O atoms from two deuteratohydroxy OD groups. Crystal data for 1:Pbcn, a=1.456 8(5) nm, b=0.659 2(2) nm, c=1.645 3(5) nm, α=90°, β=90°, γ=90°, V=1.580 0(9) nm3, Z=8, M=231.54, Dc=2.236 Mg·m-3, μ=3.070 mm-1, R1=0.043 4, wR2=0.120 6, S=1.029.
