A novel compound of 1,2-dis(1,3-diphenylpropan-2-yl)disulfane(C30H30S2,Mr=454.27)was synthesized in ethanol with 1,3-diphenyl-2-propanone as raw materials,giving high yield of product(90%).Its structure was determined by IR,1H NMR,MS,elemental analysis and X-ray diffraction.The crystal belongs to monoclinic,space group C2 with a=18.727(3),b=6.5179(9),c=13.7576(18),β=131.0610(10)o,V=1266.2(3)3,Z=2,Dc=2.136 g/cm3,μ=1.078 mm-1,F(000)=843,R=0.0490 and wR=0.1247 for 3211 observed reflections with I>2(I).X-ray analysis reveals that the molecule is not symmetrical.There exist no classical hydrogen bonds andπ-πstacking interactions.Moreover,the thermal stability of compound 3 was investigated.
Novel sulfur-containing compounds(3a–3c, 4a–4c) were obtained in ethanol with 1,3-diphenyl-2-propanone as the starting material. The advantages of this procedure were mild reaction conditions,simple protocol, and high yields. The structures of the products were characterized by IR,1H NMR, MS and elementary analysis. The crystal of the new compound 4a belongs to monoclinic, space group C2with a = 18.727(3), b = 6.5179(9), c = 13.7576(18), b = 131.0610(10)°, V = 1266.2(3)A 3, Z = 2,Dc = 2.136 g/cm3, μ = 1.078 mm-1, F(0 0 0) = 843, R = 0.0490 and wR = 0.1247 for 3211 observed reflection with I > 2δ(I). X-ray analysis reveals that the molecule is not symmetrical, the molecular structure is stabilized by weak p–p stacking interactions, and no classical hydrogen bonds can be observed.
The title compound of Cu(C14H9O3)2(C5H5N)2(C2H5OH)2(1) was synthesized via the hy- drothermal reaction of CuCl2·2H2O and 9-hydroxy-fluorene-9-carboxylic acid(HHF) with pyridine, and characterized by elemental analysis and infrared spectra. The crystal belongs to triclinic, space group P1 with a = 8.8302(12), b = 10.1625(14), c = 12.2708(17), α = 86.207(2), β = 69.562(2), γ = 64.932(2)o, V = 930.3(2) 3, Z = 1, Mr = 764.30, Dc = 1.364 g/cm3, F(000) = 399, S = 1.059 and μ(MoKα) = 0.644 mm-1. The final R = 0.0459 and wR = 0.1274 for 3414 observed reflections with I > 2σ(I). The copper atom is six-coordinated by two oxygen atoms from two different 9-hydroxy-fluorene-9-carboxylate ligands, two pyridine nitrogen atoms and two ethanol oxygen atoms, forming a distorted octahedral coordination geometry. The extensive O–H···O hydrogen bonding connects the molecules to form a one-dimensional chain structure. Between adjacent one-dimensional chains, a two-dimensional layered structure was formed by fluorene ring π-π packing interaction. Between the layers, a three-dimensional structure was formed through the π-π packing interaction of the pyridine ring. Moreover, the thermal stability and photoluminescent property of the complex has been investigated.
