Coordination polymers of Zn-II and 5-methoxy isophthalate

摘要

Solvothermal reaction of Zn(OAc)(2) and 5-methoxy isophthalic acid (H(2)MeOip) in aqueous alcohols ROH (R = H, Me, Et, or Pr-i) affords four different novel coordination polymers. Zn-2(HMeOip)(MeOip)(OAc) (1) forms as a 1D 'ribbon of rings' polymer. Zn-6(MeOip) 4.5(HMeOip)(OH)(2)(H2O)(2)center dot 5.5H(2)O (2) crystallises as a complex 3D framework. Zn(MeOip)(H2O)(2) H2O (3) is a 1D coordination polymer that contains almost planar strips of Zn(MeOip). compound 4, Zn-5(MeOip) 4(OH)(2)(H2O)(4)center dot H2O, obtained from aqueous (PrOH)-Pr-i, crystallises as a 2D polymer containing two crystallographically distinct Zn-5(OH)(2) clusters. Preliminary nitric oxide release experiments have been conducted.
