The crystal structure contains two [KTi3N4] cube-type units held together by two bridging I atoms. There is a centre of inversion located in the middle of this unprecedented discrete K2I2 unit. The geometry around K is best described as distorted trigonal prismatic, with three imide groups, two bridging I atoms and one pyridine ligand. %K Química %K Chemistry %~ Biblioteca Universidad de Alcala
