One cobalt coordinated polymer with 2-fold parallel interpenetration 3D architecture based on flexible 5-(imidazol-l-ylmethyl)isophthalate(L~(2-)) as a main ligand and 4,4’-bipyridine(bpy)as a nitrogen-containing ancillary ligand,{[CoL(bpy)_(0.5)(H_2O)_3]_2}_n(1),has been obtained under hydrothermal conditions and characterized by elemental analysis,powder X-ray diffraction(PXRD),IR spectra,Uv/vis spectra,thermal gravimetric analyses(TGA) and single-crystal X-ray diffraction.It crystallizes in monoclinic,space group C2/c with a = 26.323(4),b = 14.696(2),c = 26.630(4) A,β= 157.747(4)°,V = 3901.2(1) A~3,Z = 8,M_r= 435.27,D_c = 1.480 g/cm~3,μ= 0.923 mm~(-1),R_(int) =0.0900,F(000) = 1792,the final R= 0.0722 and wR = 0.0946 for 3641 observed reflections(I>2σ(I).Complex 1 exhibits a two-fold interpenetration 3D framework.As a single net of the 2-fold interpenetration structure,the L~(2-) anion of complex 1,as a bridging ligand,connects the Co(Ⅱ) ion to form two-dimensional layers(Co_3L_3)_n which are further linked to build a three-dimensional framework by bpy ligand.
One cobalt coordinated polymer with 2-fold parallel interpenetration 3D architecture based on flexible 5- (imidazol-l-ylmethyl) isophthalate (L ~ (2-)) as a main ligand and 4,4’-bipyridine -containing ancillary ligand, {[CoL (bpy) _ (0.5) (H_2O) _3] _2} _n (1), has been obtained under hydrothermal conditions and characterized by elemental analysis, powder X-ray diffraction , Uv / vis spectra, thermal gravimetric analyzes (TGA) and single-crystal X-ray diffraction. It crystallizes in monoclinic, space group C2 / c with a = 26.323 (4), b = 14.696 (2), c = 26.630 4) A, β = 157.747 (4) °, V = 3901.2 (1) A ~ 3, Z = 8, M_r = 435.27, D_c = 1.480 g / cm ~ 3, μ = 0.923 mm ~ (int) = 0.0900, F (000) = 1792, the final R = 0.0722 and wR = 0.0946 for 3641 observed reflections (I> 2σ (I) .Complex 1 exhibits a two-fold interpenetration 3D framework. As a single net of the 2-fold interpenetration structure, the L ~ (2-) anion of complex 1, as a bridging ligand, connects the Co (II) ion to form two-dimensional layers (Co_3L _3) _n which are further linked to build a three-dimensional framework by bpy ligand.
