Abstract: Two complexes [ZnL2(Him)2] (1) and [(Cu2L2(phen)2( μ2-Cl)2)·(Cu2( μ2-L)2(phen)2Cl2)] (2) (L=4-tolythioacetate, Him=imidazole, phen=1,10-phenanthroline) were synthesized and characterized by single crystal X-ray diffraction, elemental analysis, IR spectra and TGA. The crystal of complex 1 belongs to monoclinic, space group C2/c, with a=3.101 2(6) nm, b=0.578 2(1) nm, c=1.463 8(3) nm, β=100.962(2)°, V=2.577 0(8) nm3, Z=4, Mr=563.98, Dc=1.454 g·cm-3, F(000)=1 168, μ=1.152 mm-1, the final R=0.033 2 and wR=0.08 6 for 2 154 observed reflections with I>2σ(I). The crystal of complex 2 belongs to triclinic, space group P1, with a=1.0170 9(1) nm, b=1.0464 2(1) nm, c=1.9920 2(3) nm, α=88.649(1)°, β=84.023(1)°, γ=66.699(1)°, V=1.936 25(4) nm3, Z=1, Mr=1 841.66, Dc=1.579 g·cm-3, F(000)=940, μ=1.394 mm-1, the final R=0.030 7 and wR=0.084 1 for 7 495 observed reflections with I>2σ(I). 1 shows an undulanting-ribbon structure constructed from N-H…O hydrogen bonds. 2 consist of two dinuclear molecules bridged via chlorine and carboxylate oxygen atoms, respectively. Furthermore, C-H…O, C-H…Cl hydrogen bonding and C-H…π interactions drive 2 to be a 3D architecture. Photoluminescence studies revealed that complex 1 exhibits strong fluorescent emission bands in the solid state at room temperature. CCDC: 690004, 1; 690005, 2. |
