View source for Telluride phosphide

{{short description|Class of chemical compounds}}
The '''telluride phosphides''' are a class of [[mixed anion compounds]] containing both [[Telluride (chemistry)|telluride]] and [[phosphide]] ions (Te<sup>2−</sup> P<sup>3−</sup>). The phosphidotelluride or telluridophosphide compounds have a [TeP]<sup>3−</sup> group in which the tellurium atom has a bond to the phosphorus atom. A formal charge of −2 is on the phosphorus and −1 on the tellurium. There is no binary compound of [[tellurium]] and [[phosphorus]]. Not many telluride phosphides are known, but they have been discovered for [[noble metal]]s, [[actinide]]s, and [[group 4 element]]s.

== Structure ==
The titanium group elements form layered hexagonal crystals that can be [[Intercalation (chemistry)|exfoliated]] to [[monolayer]]s. These contain [[ditelluride]] Te<sub>2</sub><sup>2-</sup> units.<ref name=":2">{{Cite journal|last1=Chen|first1=K-W|last2=Das|first2=S|last3=Rhodes|first3=D|last4=Memaran|first4=S|last5=Besara|first5=T|last6=Siegrist|first6=T|last7=Manousakis|first7=E|last8=Balicas|first8=L|last9=Baumbach|first9=R E|date=2016-04-13|title=Uncovering the behavior of Hf 2 Te 2 P and the candidate Dirac metal Zr 2 Te 2 P|journal=Journal of Physics: Condensed Matter|volume=28|issue=14|pages=14LT01|doi=10.1088/0953-8984/28/14/14LT01|pmid=26953683|issn=0953-8984|arxiv=1602.03252|bibcode=2016JPCM...28nLT01C|s2cid=40508370}}</ref> These layered compounds can be [[Intercalation (chemistry)|intercalated]] to form [[non-stoichiometric compound]]s with [[zinc]], [[copper]] or [[cadmium]] by heating with the metals.<ref>{{Cite journal|last1=Yajima|first1=Takeshi|last2=Koshiko|first2=Masaki|last3=Zhang|first3=Yaoqing|last4=Oguchi|first4=Tamio|last5=Yu|first5=Wen|last6=Kato|first6=Daichi|last7=Kobayashi|first7=Yoji|last8=Orikasa|first8=Yuki|last9=Yamamoto|first9=Takafumi|last10=Uchimoto|first10=Yoshiharu|last11=Green|first11=Mark A.|date=December 2016|title=Selective and low temperature transition metal intercalation in layered tellurides|journal=Nature Communications|language=en|volume=7|issue=1|pages=13809|doi=10.1038/ncomms13809|issn=2041-1723|pmc=5171714|pmid=27966540|bibcode=2016NatCo...713809Y}}</ref> Actinide telluride phosphides contain diphosphide anions P<sub>2</sub>.<ref>{{Cite journal|last1=Stolze|first1=Karoline|last2=Isaeva|first2=Anna|last3=Schwarz|first3=Ulrich|last4=Doert|first4=Thomas|date=February 2015|title=UPTe, ThPTe and U 2 PTe 2 O: Actinide Pnictide Chalcogenides with Diphosphide Anions: Actinide Pnictide Chalcogenides with Diphosphide Anions|journal=European Journal of Inorganic Chemistry|language=en|volume=2015|issue=5|pages=778–785|doi=10.1002/ejic.201402951}}</ref>
