Cl-In (Chlorine-Indium) H. Okamoto The assessed In-Cl phase diagram is based primarily on [63Pal], [68Fed], and [ 87Dmi]. The intermediate phases are (1) bInCl and aInCl; (2) In3Cl4; (3) bIn2Cl3 and aIn2Cl3; (4) In5Cl9 with a possible polymorphic transition; (5) bInCl2 and aInCl2; and (6) InCl3. In(L) and InCl(L) are immiscible [63Pal]. The triple point and boiling point temperatures of Cl2 are -100.97 and -34.05 C, respectively. Two modifications, bInCl (red) and aInCl (yellow), exist in solid InCl, with a transition temperature of 120 C [66Ber]. Because liquid InCl appears to dissolve little In [68Fed], the L1 + L2 = bInCl syntectic temperature ( 212 C) must be nearly the same as the melting point of bInCl. The L = bInCl + In3Cl4 eutectic composition is uncertain because of insufficient data points in the vicinity. Considering the slopes of L2/[L1 + L2] and L/[L + In3Cl4], the eutectic temperature is shown slightly below the monotectic temperature on the In-rich side. Two formulas with similar compositions, In5Cl9 (64.3 at.% Cl) and In4Cl7 (63.6 at.% Cl), have been proposed. The former formula is tentatively accepted in the assessed diagram because the valency of In allows the formula In3I [ In2IIICl9]. Three crystal structures have been proposed for In2Cl3, as identified with (I), (II), and (III). However, the correspondence to the a and b forms in the assessed diagram is unknown. 26Kle: W.
