Abstract:
By using different transition metal containing precursors and liquid ammonia as solvent, single crystals of Sn 4 4‐ cluster containing ammoniates were grown, and three new compounds have been characterized by single crystal structure determination. K 4 Sn 4 ⋅ 8 NH 3 ( 1 ) ( P 6 3 , a =13.0370(6) Å and c =39.0889(11) Å) has been obtained by dissolving a precursor with the nominal composition “KRuSn 4 ” in liquid ammonia, and 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)°) from a similar solution of “Rb 9 Na 9 Co 16 Sn 24 “. 1 represents the last missing ammoniate of the A 4 Sn 4 compounds with heavier alkali metal cations. K 6 [OH] 2 [Sn 4 ] ⋅ 5 NH 3 ( 3 ) was crystallized from solutions of the binary Zintl phase K 12 Sn 17 in presence of AuPPh 3 Cl and 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)°), and is the Sn 4 4‐ cluster compound that appears to be stable in presence of the highest amount of hydroxide so far.
