A novel coordination polymer,{[Co(CBA)(BIMB)_(0.5)]·H_2O}_n(1,H_2CBA=4,4’-(propane-2,2-diyl)dibenzoic acid,and BIMB=4,4’-bis(1-imidazolyl)biphenyl),has been hydrothermally prepared and characterized by IR spectroscopy,elemental analysis and single-crystal X-ray diffraction.The crystal is of monoclinic system,space group P2/c with a=14.909(3),b=7.1963(15),c=24.592(5)A,β=104.312(2)°,V=2556.5(9)A~3,C_(26)H_(23)N_2O_5Co,M_r=502.39,D_c=1.305 g/cm~3,F(000)=1040,μ=0.708 mm~(-1)and Z=4.The final R=0.0580 and wR=0.1605 for3228 observed reflections(I>2σ(I)).Single-crystal structure analysis shows that complex 1 exhibits a three-dimensional 2-fold interpenetrating pillared helical-layer open framework ofα-Po topology based upon binuclear paddlewheel units.Moreover,its magnetic properties have also been investigated.
A novel coordination polymer, {[Co (CBA) (BIMB) _ (0.5)] · H_2O} _n (1, H_2CBA = 4,4’- (propane-2,2- diyl) dibenzoic acid and BIMB = 4’-bis (1-imidazolyl) biphenyl), has been hydrothermally prepared and characterized by IR spectroscopy, elemental analysis and single-crystal X-ray diffraction. The crystal is of monoclinic system, space group P2 / c with a = 14.909 B = 7.1963 (15), c = 24.592 (5) A, β = 104.312 (2) °, V = 2556.5 (9) A ~ 3, C 26 H 23 N 2 O 5 Co, M_r = 502.39, D_c = 1.305 g / cm ~ 3, F (000) = 1040, μ = 0.708 mm -1 and Z = 4. The final R = 0.0580 and wR = 0.1605 for3228 observed reflections (I> 2σ (I) . Single-crystal structure analysis shows that complex 1 exhibits a three-dimensional 2-fold interpenetrating pillared helical-layer open framework of α-Po topology based upon binuclear paddlewheel units. Moreover, its magnetic properties have also been investigated.
