Six new coordination polymers containing Co(II) and Zn(II), formulated as {[Co2(μ6-L)(μ-obtx)2]·2H2O}n (1), [Co2(μ6-L)(μ-mbtx)2]n (2), [Zn2(μ7-L)(μ-btb)0.5]n (3), {[Zn2(μ4-L)(μ-obtx)2]·2H2O}n (4), {[Zn2(μ4-L)(μ-mbtx)2]·2H2O}n (5) and {[Zn4(μ4-L)2(μ-pbtx)4]·6H2O}n (6) [H4L: (E)-1,4-bis(3,5-dicarboxyphenoxy)but-2-en, btb: 1,4-bis(1H-1,2,4-triazol-1-yl)butane, obtx: 1,2-bis((1H-1,2,4-triazol-1-yl)methyl)benzene, mbtx: 1,3-bis((1H-1,2,4-triazol-1-yl)methyl)benzene, pbtx: 1,4-bis((1H-1,2,4-triazol-1-yl)methyl)benzene] were synthesized and characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffraction techniques. To confirm the phase purity of the complexes, powder X-ray diffraction experiments were carried out. According to the results of single crystal X-ray diffraction analysis, 1 and 2 show a two-fold 3D + 3D → 3D interpenetrated frameworks with sqc27 topology while 3 exhibits 3D framework with the point symbol of (3.5.6)4( Complex 4 exhibits three-fold 3D + 3D + 3D → 3D interpenetrated framework and display bbf topology with the point symbol of (4.62)2(42.610.83). The complex 5 is a 4-connected 2D coordination polymer with the kgm topology (point symbol of 32.62.72), while 6 is two nodal 4,4-connected 3D framework with the point symbol of 86. In addition, luminescence, topological, optical and thermal properties of the complexes were investigated.
