[Rh2(DAniF)2]2-
(O2CCH2CO2)2 (DAniF =
N,N′-di-p-anisylformamidinate) react with
2-N donor linkers to give a tubular structure

changed from
[Rh2(DAniF)2(O2CCH2CO2
)]2 to the square
[Rh2(DAniF)2(O2CCO2)]4
and the linker
NCC6F4C6F4CN was
used, the compound
[Rh2(DAniF)2]4(O2C
CO2)4(NCC6F4C6
F4CN)4}n 3,
was formed, in which there are infinite tubes of square cross section
having entrained CH2Cl2 molecules.
