Tri(terf-butoxi)alkalistannates (M (O rBu)3 Sn, M = Li, Na, K, Rb, Cs) are obtained by reaction of alkali-fert-butanolates with tindi-terf-butoxide. If M equals Li or Na (1, 2) molecular com pounds are formed, which consist of two formula units. 1 crystallizes in a monoclinic cell (space group P2[/c; a = 966.5(3), b = 1819(1), c = 1014(1) pm./3 = 107.1(1)°, Z = 4); 2 is triclinic (space group PI; a = 1041(1), b = 2046(1), c = 1033(1) pm. a = 92.3(2), ß = 118.6(1), y = 108.3(3)° and Z = 4). The m olecules 1 and 2 are closely related structurally despite their different space groups. The common structural feature is a Sn2 O fiM 2 cage, which is built of two seco-norcubane Sn2 M 2 0 , units, sharing a M 2 0 2 four-membered ring. Characteristic distances are: 1: Sn—O = 209.3, L i-O = 193.0 and 211.6 pm, 2: S n -O = 210.5, N a -O = 227.4 and 240.7 pm. The ter/-butoxistannates of K, Rb and Cs (3, 4, 5) all crystallize in the orthorhombic crystal system, space group P 2 12 ,2 1 (cell constants o f 3: a = 1907(1), b — 1060(1), c — 896(1) pm, Z = 4). Contrary to the lithiumand sodium derivates 3, 4 and 5 have a polymeric structure. The one dimensional polymer consists of distorted trigonal bipyramidal S n 0 3M “cages” (substituted at the oxygen atoms by tertbutyl groups), which align in a way to allow the metal atom to have a five-fold oxygen coordina tion. The tin atoms have trigonal pyramidal coordination. While the tin-oxygen bond lengths are essentially invariant (average value 206.7 pm), the potassium-oxygen distances range from 256.4(5) pm to 318.8(6) pm.
用丁醇酸盐与丁醇酸锡反应制得三(terf-butoxi)碱酯(M (O rBu) 3sn, M = Li, Na, K, Rb, Cs)。当M等于Li或Na(1,2)时，形成由两个分子式单位组成的分子重。1在单斜晶胞中结晶(空间群P2[/c;A = 966.5(3)， b = 1819(1)， c = 1014(1) pm。/3 = 107.1(1)°，z = 4);2为三斜(空间群PI);A = 1041(1)， b = 2046(1)， c = 1033(1)。a = 92.3(2)， ß = 118.6(1)， y = 108.3(3)°，Z = 4)。m分子1和2虽然空间基团不同，但在结构上关系密切。常见的结构特征是一个sn2o膜笼，它由两个二氯苯sn2m2o单元组成，共用一个m2o四元环。特征距离为:1:Sn-O = 209.3, L -O = 193.0和211.6 pm; 2: Sn-O = 210.5, n - a -O = 227.4和240.7 pm。K、Rb和Cs(3,4,5)的ter/-butoxistannates均在空间群p212,21的正交晶系中结晶(细胞常数为:a = 1907(1)， b - 1060(1)， c - 896(1) pm, Z = 4)。与锂和钠衍生物相反，3,4和5具有聚合物结构。这种一维聚合物由扭曲的三角双锥体S n 0 3M“笼”(在氧原子上被叔丁基取代)组成，它们以某种方式排列，使金属原子具有五倍氧配位。锡原子具有三角锥体配位。虽然锡-氧键的长度基本不变(平均值为206.7 pm)，但钾-氧的距离从256.4(5)pm到318.8(6)pm不等。
