A large single crystal of a complex such as an organic carboxylic acid metal complex, which crystal is useful as an adsorbent of various gases and vapors of organic solvents and as a hydrogen-absorbing material, as well as a process for producing the crystal, is disclosed. Two layers wherein an upper layer thereof is constituted by a solution containing a metal salt and an organic carboxylic acid having a conjugated system, or a solution containing a metal salt of the organic carboxylic acid having a conjugated system, and wherein a lower layer of the two layers is constituted by a solvent which is not miscible with the solvent of the solution, is formed. Vapor of pyrazine or a substituted pyrazine from a solution of pyrazine or the substituted pyrazine is introduced into the upper layer to allow reaction, thereby forming a large single crystal(s) of the organic carboxylic acid metal complex at the interface between the two layers, which crystal(s) has(have) a longer side with a size of not less than 0.8 mm.
本发明公开了一种络合物(如有机羧酸金属络合物)的大型单晶体(该晶体可用作各种气体和有机溶剂蒸汽的吸附剂以及吸氢材料)以及生产该晶体的工艺。该晶体由两层组成,其中上层由含有金属盐和具有共轭体系的有机羧酸的溶液或含有具有共轭体系的有机羧酸的金属盐的溶液构成,两层中的下层由与溶液溶剂不混溶的溶剂构成。将吡嗪或替代吡嗪溶液中的吡嗪或替代吡嗪的蒸气引入上层,使其发生反应,从而在两层之间的界面上形成有机羧酸金属络合物的大单晶体,该晶体具有尺寸不小于 0.8 毫米的长边。
