摘要：

Two new polyhedral phenylmetallasiloxane complexes, {[PhSi(O)O](6)(Ni2+)(6)(Na+)(2)(mu(3)-OH)(2)[PhSi(O)O]6}center dot 2(BIPY)center dot 4(DMF) (1) and {[PhSi(O) O](6)(Ni2+)(3)(Na+)(6)(mu(5)-OH)(2)[PhSi(O)O](5)}center dot 7(PY)center dot 2(n-BuOH)center dot 2(H2O) (2) formed in the process of recrystallization of polyhedral phenylnickelsodiumsiloxane (Na+)(2){[PhSi(O)O](6)(Ni2+)(4)(Na+)(4)(mu(3)-OH)(2)[PhSi(O)O](6)}center dot 16(n-BuOH) (A) from DMF in the presence of 2,2-bipyridine (complex 1) or from pyridine (complex 2) are described. It is found that s-donor ligands of the pyridine series (pyridine and 2,2-bipyridine) play a crucial role in the process of dissociation of the initial metallasiloxane framework and its reassembly on a new matrix of metal ions. Not only the metal-containing cationic layer is reconstructed with a change in the number, ratio, and spatial arrangement of nickel and sodium cations, but also changes the size of cyclic siloxane ligands.
