A three-dimensional open framework constructed by rod SBUs and T-shaped linkers

A metal-coordination polymer [Co4(BPTC)2(H20)8].13H2O (1, BPTC = 3,3′4,4′-benzophenone-tetracarboxylate) containing nano-sized channels was hydrothermally synthesized. It has remarkable 3D architecture generated by unique rod-shaped SBUs(SBUs = Secondary Building Units) linked up by T-shaped ligands and present a novel constructional strategy of 3D porous metal-organic framework. One-dimensional water pipes are formed in the channels, which further stabilize the 3D framework.
