吡嗪桥联的Rh(II)羧酸盐可逆地封闭了大量的氮气。最大堵塞氮气的量分别为1.8，1.1，0.8，0.6，0.2，0.2，0.5和0.6摩尔Rh(II)盐与苯甲酸、邻羟基苯甲酸酯、间羟基苯甲酸酯、对羟基苯甲酸酯、O-甲苯甲酸酯、m-甲苯甲酸酯和对甲苯甲酸酯的摩尔数，表明这些Rh(II)羧酸盐中存在大量的微孔。从磁化率出发，类比于二羧酸铜(II)的结构，推测了线性Rh(II)羧酸盐-吡嗪的自组装形成的多孔结构，后者具有类似的气体封闭行为。
Rhodium(II) carboxylates bridged by pyrazine occlude a large amount of N2 gas, reversibly. The maximum amounts of the occluded N2 gas were 1.8, 1.1, 0.8, 0.6, 0.2, 0.2, 0.5, and 0.6 mol per one mole of rhodium(II) salt with benzoate, o-hydroxybenzoate, m-hydroxybenzoate, p-hydroxybenzoate, o-toluate, m-toluate and p-toluate, respectively, indicating the presence of a large number of micropores in these rhodium(II) carboxylates. The porous structure which is formed by self-assembly of linear rhodium(II) carboxylates–pyrazine was deduced from the magnetic susceptibilities and by analogy to the structure of copper(II) dicarboxylates which show similar gas-occlusion behavior.
