The terminal O atoms of the dichromate anion are also disordered over two positions with a refined occupancy ratio 0.586\u2005(6):0.414\u2005(6). The Cr<jats:sup>III<\/jats:sup>ion is coordinated by the four N atoms of the cyclam ligand and one bidentate oxalato ligand in a<jats:italic>cis<\/jats:italic>arrangement, resulting in a distorted octahedral geometry. The Cr\u2014N(cyclam) bond lengths are in the range 2.069\u2005(2)\u20132.086\u2005(2)\u2005\u00c5, while the average Cr\u2014O(ox) bond length is 1.936\u2005\u00c5. The macrocyclic cyclam moiety adopts the<jats:italic>cis<\/jats:italic>-V conformation. The dichromate anion has a staggered conformation. The crystal structure is stabilized by intermolecular hydrogen bonds involving the cyclam N\u2014H groups and water O\u2014H groups as donors, and the O atoms of oxalate ligand, water molecules and the Cr<jats:sub>2<\/jats:sub>O<jats:sub>7<\/jats:sub><jats:sup>2\u2212<\/jats:sup>anion as acceptors, giving rise to a three-dimensional network.<\/jats:p>","DOI":"10.1107\/s2056989017002614","type":"journal-article","created":{"date-parts":[[2017,2,16]],"date-time":"2017-02-16T13:15:29Z","timestamp":1487250929000},"page":"403-406","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":2,"title":["Crystal structure of bis[(oxalato-\u03ba<sup>2<\/sup><i>O<\/i><sup>1<\/sup>,<i>O<\/i><sup>2<\/sup>)(1,4,8,11-tetraazacyclotetradecane-\u03ba<sup>4<\/sup><i>N<\/i>)chromium(III)] dichromate octahydrate from synchrotron X-ray data"],"prefix":"10.1107","volume":"73","author":[{"given":"Dohyun","family":"Moon","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jong-Ha","family":"Choi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"329","published-online":{"date-parts":[[2017,2,17]]},"reference":[{"key":"sj5521_bb1","doi-asserted-by":"crossref","first-page":"632","DOI":"10.1134\/S0022476616030264","volume":"57","author":"Chebbi","year":"2016","journal-title":"J.
