【 摘 要 】

The synthesis, crystal structure and properties of the magnesium and calcium salts of p-anisic acid viz. [Mg(H2O)6](C8H7O3)2·2H2O (C8H7O3=p-anisate or 4-methoxybenzoate) (1) and [Ca(H2O)(C8H7O3)2] (2) are reported. The p-anisate ion is not coordinated to Mg(II) and functions as a charge balancing counter anion for the centrosymmetric octahedral [Mg(H2O)6]2+ unit in 1. The unique lattice water molecule links pairs of [Mg(H2O)6] 2+ cations and p-anisate anions with the aid of O-H···O interactions. The μ2-bridging bidentate and the μ3-bridging tetradentate binding modes of the crystallographically unique p-anisate ligands in (2) result in a two-dimensional (2-D) coordination polymer.
