Figure 4

Solid‐state molecular structure of A) the η 1‐complex [(PPh4)2][W(η 1‐2)(CO)5] and B) the η 5‐complex Ru(η 5‐2)(p‐cymene). Displacement ellipsoids are drawn at 50 % probability level. Hydrogens, counter cations, solvent molecules, and meso‐ethyl residues in B) are omitted for clarity. Selected bond lengths [pm] and angles [°] for [(PPh4)2][W(η 1‐2)(CO)5]: Sn1−N1 222.3(2), Sn1−N3 225.7(2), Sn1−N4 224.6(2), Sn1−N5 222.5(2), W1−Sn1 283.44(6), W1−Cax. 196.9(3), W1−Ceq. between 202.0(3) and 204.4(3), Sn1−N4‐plane 83.2, N1−Sn1−N4 133.41(9), N3−Sn1−N4 139.25(9), cis−N−Sn−N between 81.54(8) and 82.53(8); and Ru(η 5‐2)(p‐cymene): Sn1−N1 219.80(11), Sn1−N2 232.01(11), Sn1−N3 233.01(12), Sn1−N4 259.95(12), Sn1−N4‐plane 103.3, Ru1‐pyrrole 183.7, Ru1‐cymene 171.8, N1−Sn1−N4 126.45(4), N2−Sn1−N3 128.10(4), cis−N−Sn−N between 74.76(4) and 83.13(4).
