One Cu<jats:sup>I<\/jats:sup> ion is coordinated in a triangular coordination geometry by the N atom of the 2-ethoxypyrazine molecule and by two bridging cyanide ligands, equally disordered over two sites exchanging C and N atoms, thus forming polymeric chains parallel to the <jats:italic>c<\/jats:italic> axis. The other Cu atom is connected to two bridging cyanide groups disordered over two sites with an occupancy of 0.5 for each C and N atom, and forming an almost linear polymeric chain parallel to the <jats:italic>b<\/jats:italic> axis. In the crystal, the two types of chain, which are orthogonal to each other, are connected by cuprophilic Cu...Cu interactions [2.7958\u2005(13)\u2005\u00c5], forming two-dimensional metal\u2013organic coordination layers parallel to the <jats:italic>bc<\/jats:italic> plane. The coordination framework is further stabilized by weak long-range (electrostatic type) C\u2014H...\u03c0 interactions between cyano groups and 2-ethoxypyrazine rings.<\/jats:p>","DOI":"10.1107\/s205698901901452x","type":"journal-article","created":{"date-parts":[[2019,10,31]],"date-time":"2019-10-31T11:15:18Z","timestamp":1572520518000},"page":"1797-1800","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["Crystal structure of <i>catena<\/i>-poly[[[(2-ethoxypyrazine-\u03ba<i>N<\/i>)copper(I)]-di-\u03bc<sub>2<\/sub>-cyanido] [copper(I)-\u03bc<sub>2<\/sub>-cyanido]]"],"prefix":"10.1107","volume":"75","author":[{"given":"Sofiia V.","family":"Partsevska","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valerii Y.","family":"Sirenko","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2403-4347","authenticated-orcid":true,"given":"Kateryna V.","family":"Terebilenko","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergey O.","family":"Malinkin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Il'ya A.","family":"Gural'skiy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"329","published-online":{"date-parts":[[2019,10,31]]},"reference":[{"key":"rz5265_bb1","doi-asserted-by":"crossref","first-page":"561","DOI":"10.1002\/ange.201409672","volume":"127","author":"Aliev","year":"2015","journal-title":"Angew.
