N′
‐bis(3‐aminopropyl)ethylenediamine (BAPEN; for
I
) and homopiperazine (H‐PIP; for
II
and
III
), respectively, as the structure‐directing organic amines. The solids
I
–
III
have layered architectures. The structures of all three compounds consist of strictly alternating vertex‐sharing trigonal‐pyramidal SnO
3
and tetrahedral PO
4
moieties forming infinite layers possessing apertures bound by 4‐ and 8‐T atoms (T = Sn, P). The distorted 4‐ and 8‐membered apertures within the layers suggest the subtle influence of the lone‐pair of electrons of Sn
II
on the structure. The interlamellar space is occupied by the protonated organic amine molecules which interact with the framework through N–H
···
O hydrogen bonding. The compounds
I
–
III
bear some structural relationship to the layered zinc phosphite phases. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006) |
