In the title structure, C~12~H~10~N~4~O^2+^·2ClO~4~ ^−^·H~2~O, the dication is not planar and N—H...O hydrogen bonds link it to perchlorate anions and water molecules. In addition, N—H...O and O—H...O hydrogen bonds link these units into a three-dimensional network.
The fluorescence quantum yield and lifetime of trans-l,2-bis-(1-methyl-4-pyridinio)ethylenediperchlorate, t-BPE 2+ (C104 )2, are respectively 0.01 and < 3 ns in CH3CN. The quantum yield of trans to cis photoisomerization is 0.35\_+0.07. Iodide complexes the olefin in the ground state with an equilib
The title compound, (C~18~H~18~N~6~)~2~[Mo~8~O~26~], was produced by hydrothermal reaction of an acidified aqueous solution of Na~2~MoO~4~ and 1,1′-bis(pyridin-4-ylmethyl)-2,2′-bi-1__H__-imidazole (hereafter __L__). The structure consists of the β-octamolybdate anions having a crystallographic cente
