Metal:ligand complexes are crystallized from reaction mixtures of equimolar amounts of 4-cyano-3,6-bis(2-pyridyl)pyridazine 2 or 4-(4-bromophenyl)-3,6-bis(2-pyridyl)pyridazine 3 and silver(i) triflate. In [Ag2(2)2]2+, the two ligands adopt a head-to-tail arrangement, while a head-to-head motif is confirmed for the solid state structure of [Ag2(3)2]2+. In solution, one ligand environment is observed in each case. Silver(i) reacts with 1,3,5-tris{3,6-bis(2-pyridyl)pyridazin-4-yl}benzene 4 to give highly insoluble powders. The single crystal structures of the pseudopolymorphs (4)·Et2O and 2(4)·2MeCN·H2O are reported; in each structure, the ligand adopts the same conformation, derived from a Cs rather than C3v model structure.

The paper describes the solid state structure of a compound of composition [Cu(bipy)3][Cu(bipy)(ala) (ClO4)2]ClO4, in which both the cation and anion are octahedral complex species with copper(II) as coordination center. The cation contains three chelate rings formed by bipy; the anion contains in the quatorial plane a CuONC2 chelate ring formed by the alaninato ligand and a CuN2C2 chelate ring formed by bipy, with two monodentate perchorato ligands in axial positions completing the six-coordination. In the crystal p-p stackings lead to a supramolecular self-assembled structure.

Abstract The reaction of potassium with hexamethyldi-stannane in a refluxing solvent mixture of toluene and tetrahydrofuran (ratio 10:1) yields the red tetrahydrofuran adduct of benzyl potassium (thf)[KCH2C6H5]2 due to the metalation of toluene by the potassium trimethylstannanide intermediate. The solid state structure of (thf)[KCH2C6H5]2 contains dimers with only one potassium coordinated to a tetrahydrofuran molecule. These dimers form a polymer through benzyl bridging with shortest K-C distances at 292 pm.
