Professor Josef Goubeau in memoriamInhaltsu È bersicht. Chlordiphenylstiban (1 d) {P2 1 /c; Z = 4; a = 1191,8(1); b = 853,4(1); c = 1112,0(1) pm; b = 93,60(1)°; ±100 ± 2°C} kristallisiert isotyp zu einer Reihe homologer Verbindungen der Zusammensetzung (H 5 C 6 ) 2 E±X (E = As, X = Cl, Br, I; E = Sb, X = Br, I); der Strukturtyp des Tribenzylstibans (5 d) {Pbca; Z = 8; a = 832,1(2); b = 2681,3(5); c = 1600,9(3) pm; ±100 ± 3°C} ist vom Tribenzylmethanol, -silanol und -silan her bekannt. Demgegenu È ber weist Tribenzyldibromstiboran (6) {P2 1 /n; Z = 4; a = 938,4(2); b = 2292,4(5); c = 1019,7(2) pm; b = 112,71(1)°; ±100 ± 3°C} keine entsprechenden Beziehungen zu bereits bekannten Strukturtypen auf. Charakteristische, gemittelte Bindungsla È ngen und -winkel sind {1 d: Sb±Cl 240,9(1); Sb±C 214,0 pm; Cl±Sb±C 93,8; C±Sb±C 98,6(1)°; 5 d: Sb±C 217,5(3) pm; C±Sb±C 94,9(6)°; 6: Sb±Br 264,6; Sb±C 217,0(8) pm; Br±Sb±Br 179,4(1)°; C±Sb±C 120°; Br±Sb±C 84,8(2)°bis 94,7(2)°}. Beim Stiboran 6 deuten sich sehr schwache intermolekulare Antimon´´Brom-Wechselwirkungen (Sb´´Br 417 pm) an; sie wirken sich jedoch in auffallender Weise auf die Moleku È lkonformation aus. Element±Element Bonds. X. Studies of Chloro(diphenyl)stibane, Tribenzylstibane and Tribenzyldibromostiborane ± Molecular Structures and Isotypism Abstract. Chlorodiphenylstibane (1 d) {P2 1 /c; Z = 4; a = 1191.8(1); b = 853.4(1); c = 1112.0(1) pm; b = 93.60 (1)°; ±100 ± 2°C} crystallizes isotypically with a series of homologous (H 5 C 6 ) 2 E±X compounds (E = As, X = Cl, Br, I; E = Sb, X = Br, I); the structure type of tribenzylstibane (5 d) {Pbca; Z = 8; a = 832.1(2); b = 2681.3(5) pm; c = 1600.9(3); ±100 ± 3°C} is already known from tribenzylmethanol, -silanol and -silane. Tribenzyldibromostiborane (6) {P2 1 /n; Z = 4; a = 938.4(2); b = 2292.4(5); c = 1019.7(2) pm; b = 112.71(1)°; ±100 ± 3°C} does not show an analogous relationship to known structure types. Characteristic mean bond lengths and angles are {1 d, Sb±Cl 240.9(1), Sb±C 214.0 pm, Cl±Sb±C 93.8°, C±Sb±C 98.6(1)°; 5 d, Sb±C 217.5(3) pm, C±Sb±C 94.9(6)°; 6, Sb±Br 264.6; Sb±C 217.0(8) pm, Br±Sb±Br 179.4(1)°; C±Sb±C 120°; Br±Sb±C 84.8(2)°to 94.7(2)°}. Stiborane 6 exhibits very weak intermolecular Sb´´Br interactions of 417 pm which, however, affect the molecular conformation in a striking way.

The reaction of [(dme)LiAsH 2 ] with F 3 CSO 3 SitBu 3 yields tri-(tert-butyl)silylarsane (1). The reaction of 1 with n-butyllithium in 1,2-dimethoxyethane gives [(dme)LiAs(H)SitBu 3 ] 2 (2), whereas the lithiation of 1 in THF leads to the formation of the one-dimensional polymer [(THF)LiAs(H)SitBu 3 ] ϱ (3). The Li-As bond lengths of both of these compounds show a similar value of approximately 260 pm. However, the smaller co-
