K Ag Se
KAgSe crystallizes in the triclinic P1 space group. K(1) is bonded in a 2-coordinate geometry to three equivalent Ag(1) and two equivalent Se(1) atoms. There are a spread of K(1)-Ag(1) bond distances ranging from 2.17-3.60 Å. There is one shorter (2.54 Å) and one longer (3.23 Å) K(1)-Se(1) bond length. Ag(1) is bonded in a 6-coordinate geometry to three equivalent K(1) and three equivalent Se(1) atoms. There are a spread of Ag(1)-Se(1) bond distances ranging from 2.42-2.84 Å. Se(1) is bonded in a 5-coordinate geometry to two equivalent K(1) and three equivalent Ag(1) atoms.
