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 II—II chain, with II 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 π electrons of two pyrazole rings but does not take part in any II interactions.
