Displacement ellipsoid plot (50% probability) of the (POBBOP)Ru(CO)2 complex (POBBOP = 1,7-OP(i-Pr)2-2,6-dehydro-m-carborane) (2). (a)
A general view; (b) a view perpendicular to the (B1–B2–Ru1–C2–C3)
plane. Atoms belonging to isopropyl groups of the ligand arms have
been omitted for clarity. Selected bond distances (Å) and angles
(deg): Ru1–B1 = 2.174(3), Ru1–B2 = 2.221(3), B1–B2
= 1.720(4), Ru1–C2 = 1.939(3) Ru1–C3 = 1.915(3), B2–B4
= 1.811(3), B1–B3 = 1.796(3), B4–B7 = 1.781(3), B3–B6
= 1.785(3), B7–B6 = 1.812(4), B2–B1–Ru1 = 68.4(1),
B1–B2–Ru1 = 65.5(1), and C2–Ru1–C3 = 98.6(1).
