The crystal\u2013chemical interrelationships between parent AlB<jats:sub>2<\/jats:sub>-type, BaLiSi, ZrBeSi and the title compound are discussed using the B\u00e4rnighausen formalism. Two Ce atoms occupy sites of 3<jats:italic>m<\/jats:italic>. symmetry. The remainder,<jats:italic>i.e.<\/jats:italic>Ni, mixed Ni\/Li and Si atoms, occupy sites of \\overline{6}<jats:italic>m<\/jats:italic>2 symmetry. The environment of the Ce atom is an 18-vertex polyhedron and the Ni, Ni\/Li and Si atoms are enclosed in tricapped trigonal prisms. The title structure can be assigned to class No. 10 (trigonal prism and its derivatives) according to the Krypyakevich classification scheme [Krypyakevich (1977). In<jats:italic>Structure Types of Intermetallic Compounds<\/jats:italic>. Moscow: Nauka]. The electronic structure of the title compound was calculated using the tight-binding linear muffin-tin orbital method in the atomic spheres approximation (TB-LMTO-ASA). Metallic bonding is dominant in this compound. The strongest interactions are Ni\u2014Si and Ce\u2014Si.<\/jats:p>","DOI":"10.1107\/s2053229614011589","type":"journal-article","created":{"date-parts":[[2014,5,27]],"date-time":"2014-05-27T16:43:22Z","timestamp":1401209002000},"page":"622-626","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":1,"title":["The Ce<sub>2<\/sub>Li<sub>0.39<\/sub>Ni<sub>1.61<\/sub>Si<sub>2<\/sub>structure as a new derivative of the AlB<sub>2<\/sub>family"],"prefix":"10.1107","volume":"70","author":[{"given":"Andrij","family":"Stetskiv","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beata","family":"Rozdzynska-Kielbik","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Volodymyr","family":"Pavlyuk","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"329","published-online":{"date-parts":[[2014,5,28]]},"reference":[{"key":"ov3049_bb1","doi-asserted-by":"crossref","first-page":"3060","DOI":"10.1103\/PhysRevB.12.3060","volume":"12","author":"Andersen","year":"1975","journal-title":"Phys.
