Abstract
The structure of K3[ReO2(CN)4] has been determined by three-dimensional single-crystal neutron diffraction, and has been refined to R 0·145 for 670 independent reflections. The complex crystallizes in the triclinic space group P with a= 0·766, b= 0·745, c= 0·629 nm, α= 109·6, β= 105·9, γ= 115·4° and Z= 1. The [ReO2(CN)4]3– ion possesses an approximate octahedral arrangement around the rhenium, and contains a crystallographic centre of symmetry. The cyanide groups are carbon bonded with Re–C distance 0·2115 and 0·2132 nm, C–N distances 0·1148 and 0·1164 nm and Re–C–N angles of 179·2 and 173·7°. The Re-O distance is 0·1773 nm.Keywords
