The structure of CoI(NO)2(P(C6H5)3) has been determined at low temperature (-170°C) and is compared with the structure of a similar disordered complex, CoI(NO)2(P(C6H5)2R′) (R′ = CH2CH2P(O)(C6H5)2), which was claimed to possess strongly bent nitrosyl ligands. The title complex has two nearly linear NO groups with Co-N(1)-O(2) = 165.2 (2)° and Co-N(2)-O(2) = 163.3 (2)°. The compound crystallized in space group C2h3-C2/m with a = 17.356 (8) A?, b = 10.677 (3) A?, c = 20.998 (10) A?, β = 96.93 (1)°, and Z = 8. On the basis of 4020 unique reflections with Fo2 > σ(Fo2), the structure was refined with use of full-matrix, least-squares methods to R(F) = 0.031 and Rw(F) = 0.025.
