Electric Literature of 123640-38-0, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 123640-38-0, name is 2,6-Di(1-pyrazolyl)pyridine.

Nitrate- and nitrite-ligated 3,6-bis(imidazolyl)pyridazine-bridged dinuclear copper(II) cations with copper-copper separations similar to that in Achromobacter cycloclastes nitrite reductase
The 4,4?-bipyridine (4,4?-bipy) and 3,6-bis(imidazolyl)pyridazine (bimpydz) bridged dinuclear copper(II)-diethylenetriamine (dien) complexes, [{Cu(dien)}2(mu-diimine)][NO3] 4·xH2O (diimine = 4,4-bipy, x = 21; diimine = bimpydz, x = 05), [{Cu(dien)}2(mu-diimine)][BF4]4·4MeCN (diimine = 4,4-bipy 2 or bimpydz 6) and [{Cu(dien)}2(mu-bimpydz)]Cl4·4H2O 4, have been synthesised and characterised. Reaction of the tetrafluoroborates, 2 and 6, with NaNO2 yields the nitrites [{Cu(dien)}2(mu-diimine)][NO2][BF4] 3·xMeCN (diimine = 4,4-bipy, x = 03; diimine = bimpydz, x = 0.57). Neither the chloride nor the nitrates react with NaNO2. Structural analysis of complexes 5 and 7 has shown that although they are both based on the dinuclear cationic unit, [{Cu(dien)}2(mu-bimpydz)]4+, in 5 the bimpydz bridge adopts a transoid arrangement of imidazole molecules, whereas in 7 it adopts a cisoid arrangement, giving Cu … Cu separations of 13.28 and 12.88 A, respectively. In 5, the dications are linked by two axially co-ordinated nitrate anions, one strongly bound, the other very weakly bound, to give chains with a ladder-type motif. In 7, the dications are bridged by mu-nitrito-kappaO:kappaN moieties to form a chain with helical geometry. The copper(II)-nitrite interaction is novel; the anion bridges the weakly binding axial positions of two square-pyramidal copper atoms using the nitrogen lone pair and the syn lone pair of an oxygen.
