Luminescent [(NH(3))(4)Pt]Au(CN)(2).1.5(H(2)O), which forms from aqueous solutions of [(NH(3))(4)Pt]Cl(2) and K[Au(CN)(2)], crystallizes with extended chains of the two ions with multiple close Pt...Au (3.2804(4) and 3.2794(4) A) and Au...Au (3.2902(5), 3.3312(5), and 3.1902(4) A) contacts. Nonluminescent [(NH(3))(4)Pt]Ag(CN)(2).1.4(H(2)O) is isostructural with [(NH(3))(4)Pt]Au(CN)(2).1.5(H(2)O). Treatment of [(NH(3))(6)Ni]Cl(2) with K[Au(CN)(2)] forms [(NH(3))(2)Ni]Au(CN)(2) in which the Au(CN)(2) ions function as nitrile ligands toward nickel, which assumes a six-coordinate structure with trans NH(3) ligands. The Au(CN)(2) ions self-associate into linear columns with close Au...Au contacts of 3.0830(5) A, and pairs of gold ions in these chains make additional but longer (3.4246(5) A) contacts with other gold ions.
发光的[(NH(3))(4)Pt]Au(CN)(2).1.5(H(2)O)由[(NH(3))(4)Pt]Cl(2)和K[Au(CN)(2)]的水溶液形成，其晶体结构中两种离子形成延伸的链，存在多个紧密的Pt...Au（3.2804(4)和3.2794(4) Å）以及Au...Au（3.2902(5)、3.3312(5)和3.1902(4) Å）接触。非发光的[(NH(3))(4)Pt]Ag(CN)(2).1.4(H(2)O)与[(NH(3))(4)Pt]Au(CN)(2).1.5(H(2)O)同构。[(NH(3))(6)Ni]Cl(2)与K[Au(CN)(2)]反应生成[(NH(3))(2)Ni]Au(CN)(2)，其中Au(CN)(2)离子作为镍的腈配体，镍呈现六配位结构，配体为反式NH(3)。Au(CN)(2)离子自组装成线性柱，Au...Au紧密接触距离为3.0830(5) Å，这些链中的金离子对与其他金离子形成额外但更长（3.4246(5) Å）的接触。
