Materials Data on K2Co(SeO3)2 by Materials Project
K2Co(SeO3)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one K2Co(SeO3)2 sheet oriented in the (-1, 0, 1) direction. K1+ is bonded in a 2-coordinate geometry to four O2- atoms. There are a spread of K–O bond distances ranging from 2.11–2.74 Å. Co2+ is bonded in a distorted linear geometry to four O2- atoms. There are two shorter (1.66 Å) and two longer (2.47 Å) Co–O bond lengths. Se4+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Se–O bond distances ranging from 1.29–2.29 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one Co2+, and one Se4+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Co2+, and two equivalent Se4+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+ and one Se4+ atom.
