{{TxtAnorganik|Itrium klorida|{{chem|YCl|3}}{{Hidrat|''x''}}}}Terdapat dalam dua bentuk, yaitu hidrat ({{Chem|YCl|3}}{{Hidrat|6}}), dan anhidrat ({{Chem|YCl|3}}). Keduanya berupa padatan tak berwarna dan sangat [[Kelarutan|mudah larut]] dalam air, serta [[Higroskopi|mudah menyerap air]].

== Struktur ==
{{Chem|YCl|3}} padat mengadopsi struktur kubik, dengan ion klorida dan itrium mengisi sepertiga dari lubang oktahedral dan menghasilkaln YCl<sub>6</sub> oktahedra yang berbagi sudut dengan oktahedra yang bersebelahan, membentuk struktur berlapis.<ref>Wells A.F. (1984) ''Structural Inorganic Chemistry'' 5th edition Oxford Science Publications {{ISBN|0-19-855370-6}}</ref> Struktur ini juga dimiliki oleh beberapa senyawa, misalnya [[Aluminium klorida|AlCl<sub>3</sub>]].

== Pembuatan dan reaksi ==
{{Chem|YCl|3}} sering dibuat melalui "rute [[amonium klorida]]," dengan bahan baku {{Chem|Y|2|O|3}} atau oksiklorida atau klorida terhidrasi,<ref>

: <chem>10 NH4Cl + Y2O3 -> 2 (NH4)2[YCl5] + 6 NH3 + 3 H2O</chem>
: <chem>YCl3.6H2O + 2 NH4Cl -> (NH4)2[YCl5] + 6 H2O</chem>

Pentakloridanya terdekomposisi termal sesuai persamaan berikut:

: <chem>(NH4)2[YCl5] -> 2 NH4Cl + YCl3</chem>

Reaksi termolisis berlangsung melalui senyawa antara (NH<sub>4</sub>)[Y<sub>2</sub>Cl<sub>7</sub>].

Perlakuan [[Itrium oksida|Y<sub>2</sub>O<sub>3</sub>]]  dengan [[HCl]] dalam air menghasilkan klorida terhidrasi ({{Chem|YCl|3}}{{Hidrat|6}}). Ketika dipanaskan, garam ini menghasilkan itrium [[Oksohalida|oksiklorida]], dan tidak kembali ke bentuk anhidratnya.
