N2 - 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.
