چکیده
In the title compound, C(10)H(6)N(4)O(4), the pyridine rings are oriented at a dihedral angle of 67.8 (1)°. The O-atom pairs are trans, each displaced by a similar distance [average = 0.2331 (2) Å] out of the attached pyridine ring plane. In the crystal, inter-molecular C-H⋯O and C-H⋯N inter-actions link the mol-ecules into a three-dimensional network.

In the polymeric title complex, [Fe(C(16)H(8)O(8))(C(10)H(8)N(2))(2)](n), the iron(II) cation is coordinated by four O atoms from three different 4,4'-dicarboxybiphenyl-3,3'-di-carboxyl-ate ligands and two N atoms from two 4,4'-bipyridine ligands in a distorted octa-hedral geometry. The 4,4'-dicarboxybiphenyl-3,3'-di-carboxyl-ate ligands bridge adjacent cations, forming chains parallel to the c...

Bipyridinium residues are amongst the most intensively studied building blocks in supramolecular chemistry. They have found widespread application in molecular systems that exhibit controlled switching, rotational motion and potential for data storage. Many of these complex nanosystems harness the controllable electrochemical properties of 4,4′-bipyridinium ions (“viologens”) in either their sy...

متن کاملSynthesis of stable platinum complexes containing carborane in a carrier group for potential BNCT agents.
A series of stable platinum complexes containing closo-carborane cages in a 'carrier group', which could be potentially utilized for boron neutron capture therapy (BNCT), was successfully synthesized and characterized by various spectroscopic methods. Two ortho-closo-carborane cages were connected to the 3,3' or 4,4'-positions of 2,2'-bipyridine through ester bonds to give three carborane-linke...
