Coordination polymers with 4,4'-bipyrimidine. Using a combination of endo- and exodentate donors to build a one-dimensional Ag(I) ladder and a heterometallic Co(II)Ag(I)2 network.

چکیده
The ligand 4,4'-bipyrimidine combines a chelating bipyridine group and two terminal donor atoms into a single molecule; chelation to a single Ag(I) centre forms a square planar complex which can then form an extended planar ladder-type polymer by linking through linear Ag(I) centres whereas bis-coordination to an octahedral Co(II) centre yields a building block with four external donor nitrogen atoms which can coordinate to two distinct Ag(I) ions to form a heterometallic 2D net.

Heterometallic coordination polymers incorporating dipyrrin based heteroleptic copper and cobalt complexes: to Ag-π or not?
Using ligands based on either an acetylacetonate or a dipyrrin moiety appended with pyridyl groups, a series of novel heteroleptic copper(II) and cobalt(III) complexes combining both chelate units such as (acacpy(2))Cu(dpm-py) and (acacpy(2))Co(dpm-py)(2) (acacpy(2) = 1,3-bis(4-pyridyl)-1,3-propanedionate; dpm-py = 5-(4-pyridyl)dipyrrin) have been prepared and fully characterized. These two com...

In the title compound, [Ag(2)(C(6)H(6)NO(3)S)(2)(C(10)H(8)N(2))(2)](n), the Ag(I) atom is four-coordinated by two N atoms from two symmetry-related 4,4'-bipyridine (bipy) and two O atoms from two independent 4-amino-benzene-sulfonate (ABS) ligands. The two inter-chain Ag(I) atoms are bridged by two independent ABS ligands through weak Ag-O bonds and Ag⋯Ag attractions, forming a ladder-like chai...
