“…40 The presence of the characteristic bands at 1639 cm −1 for 1 and 2 are identified as ν CO vibrations of the amide groups. 39 The bands at 3128 cm −1 are assigned to stretching and bending vibrations of –OH groups of water molecules, which overlapped with the ν N–H vibrations of the amide moiety for 1 and 2 , respectively. 40 The thermogravimetric analyses (TGA) for CPs 1 and 2 are recorded in Fig.…”

“…The presence of the characteristic bands at 1560 and 1400 cm −1 for 1 and 2 may be attributed to the vibrations of N–H groups. 39 The strong peaks at 1334 and 1095 cm −1 for 1 and 2 suggest the ν C–N stretching vibrations of the pyridyl ring of the 3-bpah ligand. 40 The presence of the characteristic bands at 1639 cm −1 for 1 and 2 are identified as ν CO vibrations of the amide groups.…”

“…[28,29] And these complexes show particular electrocatalytic activities, fluorescence properties, antiferromagnetic behaviours, or photocatalytic activities, respectively. However, the systematic investigation about the effect of different spacers (including -(CH 2 ) 2 -, piperazine, cyclohexane, and benzene spacers) of bis-pyridyl-bis-amide ligands on the assembly and architectures of metal-organic complexes is still limited so far, [30,31] which prompts us to initiate this study.…”

Four new complexes based on 1,4-naphthalenedicarboxylic acid (1,4-H 2 NDC) and four bis-pyridyl-bis-amide ligands with various spacers (3-bpye ¼ N,N 0 -bis(3-pyridinecarboxamide)-1,2-ethane; 3-bpfp ¼ bis(3-pyridylformyl)piperazine; 3-bpcd ¼ N,N 0 -bis(pyridin-3-yl)cyclohexane-1,4-dicarboxamide; and 3-bpcb (4), have been hydrothermally synthesized. Complex 1 is a 3D coordination network and represents an 8-connected {4 20 .6 8 } topology. Complex 2 shows a 2-fold interpenetrating 3D architecture with a 6-connected {4 12 .6 3 } topology. Complexes 3 and 4 possess similar 2D sql layers with the {4 4 .6 2 } topology, but the coordination modes of 1,4-NDC ligands and the conformations of the two bis-pyridyl-bis-amide ligands are different. The adjacent layers for 3 and 4 are further linked by hydrogen bonding interactions to form 3D supramolecular networks. The successful assemblies of complexes 1-4 imply that by using the different bis-pyridyl-bis-amide ligands with diverse spacers can produce diverse metal-organic networks. Furthermore, the fluorescence and photocatalytic properties of complexes 1-4 have been investigated.

Three coordination compounds with dimensions from 0D to 2D, namely, [Co(bppdca)2(HL1)2] (1) [Co(bppdca)(L2)(H2O)]·2H2O (2) and [Co(bppdca)(L3)]·3H2O (3) [bppdca = N,N′‐bis(pyridine‐3‐yl)pyridine‐2,6‐dicarboxamide, H2L1 = 2,5‐pyridinedicarboxylic acid, H2L2 = 4,4′‐oxybisbenzoic acid, H2L3 = 2‐carboxymethylsulfanyl nicotinic acid] were hydrothermally synthesized and structurally characterized. Single crystal X‐ray diffraction analysis reveals that complex 1 is a discrete 0D complex, in which the bppdca ligand and the H2L1 act as the terminal groups to coordinate with the CoII ions. In coordination polymer 2, two bppdca ligands coordinate in anti configuration with two CoII ions to generate a 28‐membered Co2(bppdca)2 loop, which is further extended into 1D ladder‐like double chain by pairs of L2 ligands. In 3, the CoII ions are linked by bppdca ligands to generate 1D wave‐like chain, which is further connected by the L3 to form a 2D network. Finally, the coordination compounds 1–3 are extended into 3D supramolecular frameworks through the hydrogen bonding interactions. The CoII ions and the bppdca ligands in the title coordination compounds exhibit different coordination characters and conformations. The effect of organic dicarboxylates with different rigidity and length on the structures of CoII coordination compounds was investigated. In addition, the fluorescence and electrochemical behaviors of coordination compounds 1–3 were reported.
