description: K4Os2CH4O3Cl10CO crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four formaldehyde molecules and one K4Os2CH4O3Cl10 framework. In the K4Os2CH4O3Cl10 framework, there are four inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 7-coordinate geometry to two O2- and five Cl1- atoms. There are one shorter (2.64 Å) and one longer (2.82 Å) K–O bond lengths. There are a spread of K–Cl bond distances ranging from 3.08–3.37 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to nine Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.17–3.79 Å. In the third K1+ site, K1+ is bonded in a 2-coordinate geometry to two O2- and seven Cl1- atoms. There are one shorter (2.69 Å) and one longer (2.74 Å) K–O bond lengths. There are a spread of K–Cl bond distances ranging from 3.12–3.67 Å. In the fourth K1+ site, K1+ is bonded in a 10-coordinate geometry to ten Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.16–3.85 Å. There are two inequivalent Os1+ sites. In the first Os1+ site, Os1+ is bonded in a distorted square pyramidal geometry to five Cl1- atoms. There are a spread of Os–Cl bond distances ranging from 2.36–2.49 Å. In the second Os1+ site, Os1+ is bonded in a distorted square pyramidal geometry to five Cl1- atoms. There are a spread of Os–Cl bond distances ranging from 2.36–2.52 Å. C4+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.17 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to two K1+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to two K1+ and two H1+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one C4+ and one Cl1- atom. The O–Cl bond length is 3.27 Å. There are ten inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 1-coordinate geometry to three K1+ and one Os1+ atom. In the second Cl1- site, Cl1- is bonded in a 4-coordinate geometry to three K1+ and one Os1+ atom. In the third Cl1- site, Cl1- is bonded in a 4-coordinate geometry to three K1+ and one Os1+ atom. In the fourth Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four K1+ and one Os1+ atom. In the fifth Cl1- site, Cl1- is bonded in a 6-coordinate geometry to four K1+, one Os1+, and one O2- atom. In the sixth Cl1- site, Cl1- is bonded in a 3-coordinate geometry to two K1+ and one Os1+ atom. In the seventh Cl1- site, Cl1- is bonded in a 1-coordinate geometry to three K1+ and one Os1+ atom. In the eighth Cl1- site, Cl1- is bonded in a 4-coordinate geometry to three K1+ and one Os1+ atom. In the ninth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four K1+ and one Os1+ atom. In the tenth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to two equivalent K1+ and one Os1+ atom.
