%X Three novel solvent-dependent Cd(II) coordination architectures
[Cd3(BPT)2(DMF)2]·2H2O [1], [Cd3(BPT)2(DMA)2] [2], and [(CH3CH2)2NH2]·[Cd(BPT)]·2H2O [3] were obtained by the hydrothermal reaction of a C2-symmetric tricarboxylate linker, biphenyl-3,4′,5-tricarboxylic
acid (H3BPT), with cadmium nitrate in the mixed solvents
of water with N,N-dimethylformamide
(DMF), N,N-dimethylacetamide (DMA),
diethylformamide (DEF), respectively. Single-crystal X-ray diffraction
analyses reveal that complex 1 is a three-dimensional
(3D) network containing infinite Cd–O–Cd chains with
the solvent DMF molecule bridging the neighboring Cd1 and Cd2 centers.
Though complex 2 also has a 3D network containing infinite
metal-carboxylate chains, the solvent DMA molecule only coordinates
to one of the Cd(II) centers as a terminated solvent molecule. Complex 3 possesses a two-dimensional (2D) (6, 3) honeycomb type net
formed by the mononuclear metal ion and the BPT ligand, which are
further stacked in ABAB fashion through π–π interactions
into a 3D supramolecular architecture. The effect of solvents on the
formation of the coordination networks has been shown in the three
compounds obtained, and the distinction of coordination architectures
is due to the coordination abilities of solvent molecules with the
metal centers. The structure stabilities and photoluminescent properties
of the three coordination polymers have also been investigated.
