Synthesis and Crystal Structure of Two Cu II ‐benzene‐1,2,4,5‐tetracarboxylates with Three‐Dimensional Open Frameworks
Two new three‐dimensional frameworks with zeolite‐like channels were prepared in the presence of 1,6‐diaminohexane. Cu 1.5 (H 3 N–(CH 2 ) 6 –NH 3 ) 0.5 [C 6 H 2 (COO) 4 ] · 5H 2 O ( 1 ) crystallizes in the triclinic space group P $\bar{1}$ with a = 772.56(7), b = 1110.36(7), c = 1111.98(8) pm, α = 9...
