Germanium(II)‐, Tin(II)‐ and Lead(II)‐Derivatives of the polycyclic Alumosiloxane [Ph 2 SiO] 8 [Al(O)OH] 4 Five new derivatives of the polycyclic alumosiloxane [Ph 2 SiO] 8 [Al(O)OH] 4 have been synthesized by replacement of the protic hydrogen atoms on the hydroxy‐groups attached to the aluminium atoms by the divalent group 14 elements germanium, tin and lead. The compounds can be divided in those with one metal atom per alumosiloxane moiety, [Ph 2 SiO] 8 [Al(O)OH] 2 [AlO 2 ]M (M=Ge, Sn), and those with complete substitution of the protic hydrogen atoms by metal atoms like [Ph 2 SiO] 8 [AlO 2 ] 4 M 2 (M= Sn, Pb). Always one element of the series Ge, Sn, Pb is missing in the two types of compounds. Crystal structure analyses of [Ph 2 SiO] 8 [Al(O)OH] 2 [AlO 2 ] 2 M · 2 C 4 H 8 O 2 (M= Ge ( 1 ), Sn ( 2a )), [Ph 2 SiO] 8 [Al(O)OH] 2 [AlO 2 ] 2 Sn · 2 THF ( 2b ) and [Ph 2 SiO] 8 [AlO 2 ] 4 M 2 (M= Sn ( 3 ), Pb ( 4 )) have been performed elucidating either polycyclic basket‐type ( 1 , 2a , 2b ) or closed polyhedral structures ( 3 , 4 ).
