A novel coordination polymer [(ZnTPP)(3) L(1)](n)center dot(DMF)(2n) 1 (ZnTPP = zinc(II) tetraphenylporphyrinate) has been hydrothermally synthesized from a tetrapyridyl ligand N,N,N',N'-tetra(4-pyridyl)-1,4-phenylenediamine (L(1)) and characterized by elemental analysis. IR, and single-crystal X-ray diffraction analyses. In the crystal, L(1) utilizes all four pyridyl N atoms to coordinate at the axial positions of two different ZnTPP units. The first utilizes two axial positions for coordination, and the second coordinates at only one of the axial positions. Thus, the former ZnTPP units and two pyridyl nitrogens of L(1) ligands are linked alternately to afford a zigzag chain, and two of the latter porphyrin units are appended to both sides of each repeating unit of the zigzag chain by coordination to the remaining two nitrogens of each L(1) ligand. Interestingly, the appended porphyrins form two straight lines at both sides of the zigzag chain by the linkage of pi center dot center dot center dot pi interactions between the phenyl rings. Finally, a triple chain is formed. The solid state emission of 1 is also studied. (C) 2010 Elsevier B.V. All rights reserved.
