Two rare {M₂(MoO₄)₂}_n chain-containing molybdate-based metal–organic complexes with a bis-pyrazole-bis-amide ligand: fluorescent sensing and photocatalysis performance

Abstract

Two molybdate-based complexes containing {M2(MoO4)2}n (M = Co or Zn) chains were obtained, which demonstrated different properties: excellent photocatalytic degradation performance of cationic dyes for 1 and fluorescence sensing behavior for 2.

Statistical analysis of PN clusters in Mo/VFe protein crystals using a bond valence method toward their electronic structures

“…The bond valence method was first used to analyze inorganic crystal structures 32–36 and was gradually applied in other fields. 37–41 It can be traced back historically to a proposal by Pauling. 42 It is a classic and valid approach for assessing the charge between a metal atom and its bound coordinated atoms, and has proved an effective method to evaluate the electron density in a delocalized system 43 and the oxidation states of metals in a metalloprotein.…”

Two polymolybdate-directed Zn(ii) complexes tuned by a new bis-pyridine-bis-amide ligand with a diphenylketone spacer for efficient ampere sensing and dye adsorption

“…18–20 Currently, various bis-amide derivatives with multiple N/O sites have been introduced to construct POMOCs. 21–23 For example, a flexible bis-pyrazine-bis-amide ligand, N , N ′-bis(2-pyrazinecarboxamide)-1,4-butane, was designed by Li's group, and furthermore a novel 3D metal–organic framework was constructed. 24 Our group obtained a 1D chain complex with α–γ-type [Mo 8 O 26 ] 4− anions by introducing a flexible bis-pyrazole-bis-amide ligand.…”
