两种新的杂配金属-有机骨架材料对H2和乙醇表现出较强的吸附性能。[Co2（L1）（bdc）2 ]，其中L1=N1，N4 -双（4-吡啶甲基）-2，5-二甲基苯-1，4-二胺，bdc为苯-1，4-二甲酸酯，具有pcu拓扑结构的双层互穿层柱结构。它具有阶梯式滞后EtOH吸附，这可能与去溶剂化和再溶剂化时发生的复杂相和结构转化行为有关，包括柔性L1配体几何形状的主要构象变化。[Co2（L1）（bpdc）2 ]，其中bpdc=联苯基-4，4 '-二羧酸酯，具有独特的六连接的自连接骨架结构。发生溶剂化变化而没有显著的结构变化，并且部分水解的材料结合其自身的分解产物作为客体。
Two new heteroleptic metal-organic framework materials show strong adsorption of H2 and ethanol. [Co2 (L1)(bdc)2 ], where L1=N1 ,N4 -bis(4-pyridinylmethyl)-2,5-dimethylbenzene-1,4-diamine and bdc is benzene-1,4-dicarboxylate, has a twofold interpenetrating pillared layer structure with pcu topology. It has a stepped, hysteretic EtOH adsorption that can be related to complicated phase and structural transformation behaviour that occurs on de-solvation and re-solvation, including major conformational changes to the geometry of the flexible L1 ligand. [Co2 (L1)(bpdc)2 ], where bpdc=biphenyl-4,4'-dicarboxylate, has a unique six-connected self-catenating framework structure. Solvation changes occur without significant structural change and a partially-hydrolysed material binds its own decomposition products as guests.
