(A) ORTEP plot of the cation of complex RuL1. Hydrogen
atoms, counterion, and solvent molecules are omitted for clarity.
Ellipsoids have been represented at 50% probability. Selected bond
lengths (Å) and angles (deg) for RuL1: Ru–C48:2.016(3),
Ru–N5:2.103(2), Ru–N1:2.068(2), Ru–N2:2.168(2),
Ru–N3:2.054(2), Ru–N4:2.050(2). C48–Ru–N5:79.34(9),
N1–Ru–N2:78.34(8); N3–Ru–N4:80.01(8).
CCDC reference number for RuL1: 2387012. (B) π–π
and C–H···π interactions in the packing
of RuL1 in the crystal, indicated as dashed black lines. Details of
these interactions, including the symmetry transformations, are given
in Tables S3 and S4 (Cg = ring
centroid).
