- Two novel three-dimensional Zn-MOFs (zinc metal-organic frameworks), Zn5(mu 3-OH)(BTC)3(Phen)4 center dot 5H2O (denoted as HUT-11) and Zn4(mu 4-O)(BTC)2(Phen)2 center dot 4H2O (denoted as HUT-12), have been synthesized by metalligand-directed assembly under hydrothermal conditions. Here, BTC and Phen are denoted as 1,3,5-benzenetricarboxylate and phenanthroline. HUT-11 contains two kinds of secondary building units (SBUs), Zn3(mu 3-OH)(COO)5 clusters and Zn2(COO)4 clusters. This material exhibits a new three-dimensional (3,4,5)-connected topology with the Schlafli symbol (4.6.8)2(4.82)(4.64.85)(42.62.82). Two perpendicular planes cross at five coordinated Zn1-Zn3-Zn5 nodes, giving a new three-dimensional network. HUT-12 is composed of Zn4(mu 4-O)(COO)6 clusters as the secondary building units and displays a two-dimensional (3,6)-connected TiS2 related net topology with the Schlafli symbol (42.6)(44.62.88.10). Both MOFs show blue light emission and a high thermal stability above 673 K.
