By using different transition metal containing precursors and liquid ammonia as solvent, single crystals of Sn44- cluster containing ammoniates were grown, and three new compounds have been characterized by single crystal structure determination. K4Sn4 ⋅ 8 NH3 (1) (P63, a=13.0370(6) Å and c=39.0889(11) Å) has been obtained by dissolving a precursor with the nominal composition “KRuSn4” in liquid ammonia, and Rb2Na2Sn4 ⋅ 4.8 NH3 (2) (Pc, a=9.4005(3) Å, b=15.3663(6) Å, c=12.7312(6) Å, β=94.675(3)°) from a similar solution of “Rb9Na9Co16Sn24“. 1 represents the last missing ammoniate of the A4Sn4 compounds with heavier alkali metal cations. K6[OH]2[Sn4] ⋅ 5 NH3 (3) was crystallized from solutions of the binary Zintl phase K12Sn17 in presence of AuPPh3Cl and cryptand[2.2.2] (P21/c, a=10.3655(1) Å, b=12.7489(2) Å, c=16.9137(3) Å, β=103.212(2)°), and is the Sn44- cluster compound that appears to be stable in presence of the highest amount of hydroxide so far.

Sn4簇化合物在液氨中溶解度的研究

以不同的含过渡金属前驱体和液氨为溶剂,生长了含氨盐的Sn 4 4-簇单晶,并通过单晶结构测定对三种新化合物进行了表征。K 4 Sn 4  ⋅ 8 NH 3 ( 1 ) ( P 6 3 , a =13.0370(6) Å and c =39.0889(11) Å) 已通过将标称组成为“KRuSn 4 ”的前体溶解在液氨中获得, 和 Rb 2 Na 2 Sn 4  ⋅ 4.8 NH 3 ( 2 ) (Pc , a =9.4005(3) Å, b =15.3663(6) Å, c =12.7312(6) Å, β =94.675(3)°) 来自“Rb 9 Na 9 Co 16 Sn 24 ”的类似溶液。1代表具有较重碱金属阳离子的A 4 Sn 4化合物的最后缺失的氨化物。K 6 [OH] 2 [Sn 4 ] ⋅ 5 NH 3 ( 3 ) 是在 AuPPh 3存在下从 Zintl 二相 K 12 Sn 17 的溶液中结晶出来的Cl 和 cryptand[2.2.2] ( P 2 1 / c , a =10.3655(1) Å, b =12.7489(2) Å, c =16.9137(3) Å, β =103.212(2)°), 并且是Sn 4 4-簇化合物在迄今为止最高量的氢氧化物存在下似乎是稳定的。
