A new metal-organic polymer Mn_(3)(BTC)_(2)(H_(2)O)_(9)·(H_(2)O) was synthesized by reaction of the metal ions Mn(Ⅱ) with 1,3,5-benzenetricarboxylic acid(H_(3)BTC) in a mixed solution of DMF/C_(2)H_(5)OH/(H_(2)O) and crystallized.The crystal belongs to monoclinic system,space group C2/c with a=1.901 4(4) nm,b=0.740 23(15) nm,c=2.044 9(4) nm,β=97.18(3)°,V=2.855 5(10) nm~(3),Z=4,D_c=1.766(g/cm~3),μ(Mo Kα)=1.401 mm~(-1),R[I>2σ(I)]=0.072 7,wR=0.235 1 for 2 419 independent reflections with goodness-of-fit 1.046. Its structure possesses bilayer architectures constructed from Mn ions linked infinite Mn(BTC) chains which were build up from BTC ligand as the “T-shape” module and Mn as the linear module.The hydrogen-bond and π-π stacking interactions between bilayers make them three-dimensional channel-like interpenetrated frameworks.
A new metal-organic polymer Mn_ (3) (BTC) _ (2) (H_ (2) O) _ (9) · (H_ (2) O) was synthesized by reaction of the metal ions Mn , 3,5-benzenetricarboxylic acid (H_ (3) BTC) in a mixed solution of DMF / C 2 H_ (5) OH / (H_ (2) O) and crystallized.The crystal belongs to monoclinic system, space group C = 2.044 9 (4) nm, β = 97.18 (3) °, V = 2.855 5 (10) nm ~ (3) ), Z = 4, D_c = 1.766 (g / cm ~ 3), μ (Mo Kα) = 1.401 mm -1, R [I> 2σ (I)] = 0.072 7 and wR = 0.235 1 for 2 419 independent reflections with goodness-of-fit 1.046. Its structure possesses bilayer architectures constructed from Mn ions linked to an infinite Mn (BTC) chains which were build up from BTC ligand as the “T-shape” module and Mn as the linear module . The hydrogen-bond and π-π stacking interactions between bilayers make them three-dimensional channel-like interpenetrated frameworks.
