摘要
Sodium 5-hydroxy-4'-methoxyisoflavone-3'-sulfonate was synthesized by sulfonation of pallidiflorin and assembled with Zn-II, Mg-II, and Co-II to form [Zn(H2O)(6)](C16H11O4SO3)(2)center dot 2H(2)O (1), [Mg(H2O)(6)](C16H11O4SO3)(2)center dot 2H(2)O (2), and [Co (H2O)(6)] (C16H11O4SO3)(2)center dot 2H(2)O (3). In the crystal structures of 1-3, [M(H2O)(6)](2+), C16H11O4SO3-, and H2O form intermolecular and intramolecular hydrogen bonds. The hydrogen bonds, pi-pi stacking interactions, and electrostatic interactions between the cations and anions link compounds 1-3 into three-dimensional structures. The thermal stabilities of 1-3 were also investigated.
