MetadataShow full item record
In the crystal structures of terpyridyl complexes from the Cambridge Structural Database (CSD) stacking interaction between the pyridine fragments were studied. Square-planar complexes where the distance between the centers of two pyridine fragments was below 4.6 angstrom were retrieved from CSD. With this search 68 crystal structures with 167 interactions were found. In the interactions one, two or three pyridine fragments of one complex can be involved in overlapping with pyridine fragments of the other complex.
