Solvothermal reaction of Zn(OAc) 2 and 5-methoxy isophthalic acid (H 2 MeOip) in aqueous alcohols ROH (R = H, Me, Et, or i Pr) 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 (H 2 O) 2 ·5.5H 2 O ( 2 ) crystallises as a complex 3D framework. Zn(MeOip)(H 2 O) 2 H 2 O ( 3 ) is a 1D coordination polymer that contains almost planar strips of Zn(MeOip). compound 4 , Zn 5 (MeOip) 4 (OH) 2 (H 2 O) 4 ·H 2 O, obtained from aqueous i PrOH, crystallises as a 2D polymer containing two crystallographically distinct Zn 5 (OH) 2 clusters. Preliminary nitric oxide release experiments have been conducted. Four different coordination polymers were prepared by reaction of Zn(OAc) 2 and 5-methoxy isophthalic acid using various aqueous/aqueous alcohol solvent systems.
