The title compound, (5,10,15,20-tetra-4-pyridylporphyrinato)zinc(II) 1,2-dichlorobenzene disolvate, [Zn(C40H24N8)]·2C6H4Cl2, contains a clathrate-type structure. It is composed of two-dimensional square-grid coordination networks of the self-assembled porphyrin moiety, which are stacked one on top of the other in a parallel manner. The interporphyrin cavities of the overlapping networks combine into channel voids accommodated by the dichlorobenzene solvent. Molecules of the porphyrin complex are located on crystallographic inversion centres. The observed two-dimensional assembly mode of the porphyrin units represents a supramolecular isomer of the unique three-dimensional coordination frameworks of the same porphyrin building block observed earlier. The significance of this study lies in the discovery of an additional supramolecular isomer of the rarely observed structures of metalloporphyrins self-assembled directly into extended coordination polymers without the use of external ligand or metal ion auxiliaries.

The discrete complex [(Cul)2 (pyzCN)4] (1) and the coordination polymers 1∞ [CuI(pyzCN)] (2) and 3∞ [(CuX)3 (pyzCN)2] (3, 4; X = Br, Cl) may be prepared from the respective copper(I) halide CuX and 2-cyanopyrazine (pyzCN) by self-assembly in acetonitrile solution at 100- 120°C. Whereas 2 exhibits 1 [Cul] staircase double chains as its characteristic substructure, the three-dimensional networks of 3 and 4 contain single zigzag CuX strings. The influence of the copper(I) halide on both the connectivity pattern and the dimensionality of a resulting coordination network is particularly apparent for the 1:1 complexes 1∞ [CuI(pymMe)] (5), 3∞ [(CuBr)3(pymMe)3] (6) and 2∞ [CuCl(pymMe)] (7), which were generated by reaction of CuX with 4-methylpyrimidine (pymMe) under reaction conditions similar to those above.

AbstractThe crystal and molecular structure of [Cu(nif)2(4-PM)2]·CH3OH (1) and [Cu(2-Clbz)2(4-PM)2(H2O)] (2), (where nif = niflumate anion, 2-Clbz = 2-chlorobenzoate anion and 4-PM is the 4-pyridylmethanol), have been determinated by X-ray crystallography. The Cu2+ cation in (1), is coordinated by two pairs of oxygen atoms from asymmetric bidentate niflumate anions and by a pair of pyridine nitrogen atoms from monodentate 4-pyridylmethanol ligands in trans position forming an extremely elongated bipyramid. The Cu2+ cation in (2), is coordinated by a pair of oxygen atoms from monodentate 2-chlorobenzoate anions, further by a pair of pyridine nitrogen atoms from monodentate 4-pyridylmethanol ligands and finally by a water oxygen atom forming a tetragonal-pyramidal coordination polyhedron. The molecules of both complexes in crystal structures are linked by O-H…O hydrogen bonds, which created a three-dimensional hydrogen-bonding networks. The Π-Π stacking interactions are also observed in crystal structures of complex 2. The spectral properties (IR and electronic spectra) of both complexes were also investigated.
