The title compound, [Co(C7H5O3)2(C6H6N2O)2(H2O)2], forms a three‐dimensional hydrogen‐bonded supramolecular structure. The CoII ion is in an octahedral coordination environment comprising two pyridyl N atoms, two carboxylate O atoms and two O atoms from water molecules. Intermolecular N—H...O and O—H...O hydrogen bonds produce R22(8), R22(12) and R22(14) rings, which lead to two‐dimensional chains. An extensive three‐dimensional supramolecular network of C—H...O, N—H...O and O—H...O hydrogen bonds and C—H...π interactions is responsible for crystal structure stabilization. This study is an example of the construction of a supramolecular assembly based on hydrogen bonds in mixed‐ligand metal complexes. 相似文献

The title compound, [Zn(C32H16N8)(C5H6N2)]·2C4H8O, consists of one (phthalocyaninato)zinc (ZnPc) unit, a coordinated 4‐aminopyridine (4‐ap) molecule and two tetrahydrofuran (THF) solvent molecules. The central Zn atom is (4+1)‐coordinated by four isoindole N atoms of the Pc core and by the pyridine N atom of 4‐aminopyridine. The Zn atom is displaced by 0.4464 (8) Å from the isoindole N4 plane towards the pyridine N atom. The crystal structure is stabilized by intermolecular amine–phthalocyaninate N—H...N hydrogen bonds and π–π interactions between the aggregated Pc rings, which form molecular layers, and by weak van der Waals interactions between the layers. As well as hindering the aggregation of ZnPc molecules by occupying an axial position, the amino group will add new interactions which will favor applications of ZnPc, for example, as a sensitizer of photodynamic therapy. 相似文献
