Coordination polymers derived from 5-benzyloxy isophthalic acid (H2BzOip) are rare, with only three reported that do not contain additional bridging ligands, of which two M2(BzOip)2(H2O) (M = Co and Zn) are isomorphous. It was hoped that by varying the solvent system in a reaction between H2BzOip and M(OAc)2 (M = Co and Zn), from water to a water/alcohol mixture, coordination polymers of different topology could be formed. Instead, two polymorphs of the existing M2(BzOip)2(H2O) (M = Co and Zn) were isolated from aqueous methanol and aqueous ethanol, in which a small number of guest solvent molecules are present in the crystals. These guest water molecules disrupt the hexaphenyl embrace motif, leading to varying degrees of disorder of the benzyl groups.

Two salts of the chlorhexidine di-cation (H₂CHx²⁺) - (H₂CHx)(SO₄)·3H₂O and (H₂CHx)(CO₃)·4H₂O - have been synthesised and characterised crystallographically.

The topology of coordination polymers containing 5-alkoxy isophthalic acids and first row transition metals was found to be dependent on the combination of solvent system used and length of the alkyl chain. Four different framework types were identified: Phase A, M6(ROip)5(OH)2(H2O)4·xH2O (M = Co and R = Et, Pr, or nBu, or M = Zn and R = Et); Phase B, M2(ROip)2(H2O) (M = Co or Zn and R = Et, Pr, nBu, or iBu, or M = Mn and R = nBu or iBu); Phase C, Zn3(EtOip)2(OH)2; and Phase D, Zn2(EtOip)2(H2O)3. Preliminary screening of the NO storage and release capabilities of the Co-containing materials is also reported.

The synthesis and characterisation of five coordination polymers - Ni₂(mip)₂(H₂O)₈·2H₂O (1), Zn₆(mip)₅(OH)₂(H₂O)₄·7.4H₂O (2), Zn₆(mip)₅(OH)₂(H₂O)₂·4H₂O (3), Mn(HMeOip)₂ (4), and Mn₃(tbip)₂(Htbip)₂(EtOH)₂ (5) - are reported. Preliminary nitric oxide release data on compounds 2 and 3 are also given.
