manganese complex%crystal structure%polymeric complex benzenetetracarboxylate
The single crystals of the title compound were obtained from a reaction of MnCO3,benzenetetracarboxylic acid (H4BTC)and imidazole in an aqueous solution.The crystal of Mn(II)complex (C28H34Mn2N12O12(4H2O,Mr=912.62) belongs to tricli nic,space group Pī with a=10.036(1),b=10.650(1),c=11.102(1)A,α=114.72(2),β=95.75(1),γ=108.46(2)°,V=984.2(2)A3,Z=1,Dc=1.540 g/cm3,F(000)=472,μ(MoKα)=0.726 mm-1,R=0.0409 and wR=0.1166 for 3909 observed reflections (I>2σ(I)).The crystal consists of the polymeric Mn(II)complex anions and discrete Mn(II) complex cations,both with normal octahedral coordination geometry.Each BTC bridges two Mn(II) atoms to form the anionic polymeric chain,and the cations distribute be-tween the chains and link them through both classic and weak C-H…O H-bonding.
