(Hydridotripyrazolylborato)iodo{(1,2,5,6-[eta])-1-[(Z)-1-iodo-2-phenylethenyl]cycloocta-1,5-diene}ruthenium(II)-diiodine (2/1)

Abstract: The title compound, [Ru(C9H10BN6)I(C16H17I)]·0.5I2, is a cocrystal of an iodine-bearing neutral ruthenium complex and diiodine. The centrosymmetric diiodine molecule links a pair of Ru complexes via halogen bonds to the Ru-bound iodide anions, thus forming a linear I...I-I...I chain, with I...I distances of 2.837 (1) Å for the inner bond and 3.486 (1) Å for the two outer interactions. The C-bound iodine interacts with the [pi] electrons of two pyrazole rings but does not take part in any I...I interactions.
