Crystal structure of (2,11-diaza[3.3](2,6)pyridinophane-κ⁴N,N′,N′′,N′′′)(1,6,7,12-tetraazaperylene-κ²N¹,N¹²)ruthenium(II) bis(hexafluoridophosphate) acetonitrile 1.422-solvate

Abstract

The highlighted ruthenium complex forms discrete dimers by π–π stacking inter­actions and hydrogen bonds. This combination of inter­actions results in an unusual nearly face-to-face π–π stacking mode.

Heterodinuclear Ruthenium(II) Complexes of the Bridging Ligand 1,6,7,12‐Tetraazaperylene with Iron(II), Cobalt(II), Nickel(II), as well as Palladium(II) and Platinum(II)

“…Distorted octahedral coordination arrangements are found around the ruthenium, iron, and nickel ions, displaying the highest distortions from ideal octahedral environment by the deviations of the N amine –M–N amine angles from the ideal value of 180°, caused by the L‐N 4 Me 2 ligand 3,5,6. In all complexes, the bridging ligand tape is almost planar, as earlier reported for the analogous homodinuclear ruthenium(II) complex [ 1 ](PF 6 ) 4 3.…”
