Syntheses and crystal structures of two coordination polymer based on 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene

Abstract

Two novel coordination polymers, [Zn2(CAM)2(Titmb)] (I) and [Zn4Co(OH)2(BTEC)2 (Titmb)2(H2O)2] · 2H2O (II) (H2CAM = camphor acid, H4BTEC = 1,2,4,5-benzenetetracarboxylic acid, and Titmb = 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene), have been hydrothermal prepared and characterized by IR spectroscopy, elemental analysis, and single-crystal X-ray diffraction. Complex I displays an unusual three-dimensional (3,4,6)-connected network with (4.64.8)2(42.64.89)(62.8)2 topology. Complex II exhibits an interesting heterometallic 3D metal-organic framework. Moreover, the luminescent properties of I have been investigated in the solid state at room temperature.
