(NH4)2AgX3 (X = Br, I): 1D Silver Halides with Broadband White Light Emission and Improved Stability

“…Compared to (NH 4 ) 2 AgBr 3 , (NH 4 ) 2 AgI 3 features slightly less distorted tetrahedra, with Ag–I bond lengths ranging from 2.8345(7) to 2.8647(4) Å and I–Ag–I angles from 104.982(19) to 109.505(12)°. These bond lengths are within the expected range and are consistent with that reported for K 2 AgI 3 , where Ag–I bond lengths range from 2.8093 to 2.8525 Å and I–Ag–I angles are from 103.90 to 113.83° . Note that the K 2 AgI 3 type structure is similar to the K 2 CuCl 3 type structure adopted by the A 2 CuX 3 family, which have recently been reported as ultrabright blue emitters with prospective applications in solid-state lighting and radiation detection applications. ,,, The differences between the two structure types are in the packing of the chains relative to the A cationic site …”

“…■ RESULTS AND DISCUSSION (NH 4 ) 2 AgBr 3 and (NH 4 ) 2 AgI 3 are isostructural compounds crystallizing with the K 2 AgI 3 type structure in the Pnma space group (Tables S1−S3). 24 Their structure consists of 29 Note that the K 2 AgI 3 type structure is similar to the K 2 CuCl 3 type structure adopted by the A 2 CuX 3 family, which have recently been reported as ultrabright blue emitters with prospective applications in solidstate lighting and radiation detection applications. 4,13,14,17 The differences between the two structure types are in the packing of the chains relative to the A cationic site.…”

Crystal structures and ionic conductivities of ternary derivatives of the silver and copper monohalides—II: ordered phases within the (AgX)x–(MX)1−x and (CuX)x–(MX)1−x (M=K, Rb and Cs; X=Cl, Br and I) systems

“…These are Rb 2 AgCl 3 [28], Cs 2 AgCl 3 [29], Rb 2 AgBr 3 [17], Cs 2 AgBr 3 [17], K 2 AgI 3 [16,17,30,31], Rb 2 AgI 3 [17,30,32], Cs 2 AgI 3 [17], K 2 CuCl 3 [21,29,33], Rb 2 CuCl 3 [34], K 2 CuBr 3 [35], Rb 2 CuBr 3 [21] and Rb 2 CuI 3 [17]. Of these, only Rb 2 AgCl 3 [28], K 2 AgI 3 [31] and Rb 2 AgI 3 [32] have been the subject of full structural characterization, in which positional parameters have been determined by leastsquares methods. However, the unit cell dimensions of a number of the other compounds have been reported [29,30] and it is generally accepted that all adopt one of three closely related structure types, which we label I, II and III.…”
