Abstract

(K2C2N2O3)2MoO2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of two molybdenum (iv)oxide molecules and one K2C2N2O3 framework. In the K2C2N2O3 framework, there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 7-coordinate geometry to four N+2.50- and three O2- atoms. There are a spread of K–N bond distances ranging from 2.85–3.11 Å. There are a spread of K–O bond distances ranging from 2.68–3.31 Å. In the second K1+ site, K1+ is bonded in a 7-coordinate geometry to three N+2.50- and four O2- atoms. There are a spread of K–N bond distances ranging from 2.97–3.11 Å. There are a spread of K–O bond distances ranging from 2.69–2.96 Å. There are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a single-bond geometry to one N+2.50- atom. The C–N bond length is 1.18 Å. In the second C4+ site, C4+ is bonded in a single-bond geometry to one N+2.50- atom. The C–N bond length is 1.18 Å. There are two inequivalent N+2.50- sites. In the first N+2.50- site, N+2.50- is bonded in a distorted single-bond geometry to four K1+ and one C4+ atom. In the second N+2.50- site, N+2.50- is bonded in a distorted single-bond geometry to three K1+ and one C4+ atom. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three K1+ and one O2- atom. The O–O bond length is 1.27 Å. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two K1+ and one O2- atom. In the third O2- site, O2- is bonded in a distorted water-like geometry to two K1+ atoms.
