合成了一种新颖的等网格草酸根基锰（II）-铜（II）开放金属有机骨架H（2）O@iso1，其特征在于具有交替开放和闭合的八边形孔的柱撑正方形/八边形层结构.开放骨架拓扑结构在分离小气体（CO（2）相对于CH（4））和蒸气分子（CH（3）OH相对于CH（3）CN和CH（3）CH（2）OH）中负责大的选择性。H（2）O@iso1具有长程三维铁磁有序结构，其临界温度随客体分子的变化而急剧变化[T（C）< 2.0 K（CO（2）@iso1 and CH（4）@iso1）and T（C）= 6.5（CH（3）OH@iso1）and 21.0 K（H（2）O@iso1）].
A novel isoreticular oxamato-based manganese(II)-copper(II) open metal-organic framework H(2)O@iso1 featuring a pillared square/octagonal layer structure with alternating open and closed octagonal pores has been rationally prepared. The open-framework topology is responsible for a large selectivity in the separation of small gas (CO(2) over CH(4)) and vapor molecules (CH(3)OH over CH(3)CN and CH(3)CH(2)OH). H(2)O@iso1 displays a long-range three-dimensional ferromagnetic ordering with a drastic variation of the critical temperature as a function of the guest molecule [T(C) < 2.0 K (CO(2)@iso1 and CH(4)@iso1) and T(C) = 6.5 (CH(3)OH@iso1) and 21.0 K (H(2)O@iso1)].
