Synthesis and characterization of binuclear half-sandwich metal (Co, Ir and Ru) complexes containing ancillary ortho-carborane-1,2-dithiolato ligands was written by Liu, Shuang;Zhang, Jiasheng;Wang, Xin;Jin, Guo-Xin. And the article was included in Dalton Transactions in 2006.HPLC of Formula: 15420-02-7 This article mentions the following:
Pyrazine-, 4,4′-bipyridine-, 1,2-ethenediylbis-4,4′-pyridine-, 2,5-bis(4-pyridinyl)-1,3,4-oxadiazole-bridged binuclear half-sandwich Co, Ir and Ru o-carborane-1,2-dithiolates were prepared by reacting of the corresponding monomeric η5-C5Me5– (for Co and Ir) and η6-p-cymene (for Ru) dithiolates with the heterocyclic bidentate ligands. The prepared complexes are soluble and air-stable. The complexes [[(p-cymene)Ru[S2C2(B10H10)]]2(μ-pyrazine-κN1κN4)] (4), [[Cp*Co[S2C2(B10H10)]]2(μ-pyrazine-κN1κN4)] (5), [[Cp*Co[S2C2(B10H10)]]2(μ-4,4′-bipyridine)] (6), [Cp*Co[S2C2(B10H10)]]2(μ-bpe) (7, bpe = 4-C5H4NCH:CHC5H4N-4) and [[Cp*Ir[E2C2(B10H10)]]2(μ-bpo)] [8a,b; E = S, Se; bpo = 2,5-bis(4-pyridinyl-κN)-1,3,4-oxadiazole], in which organometallic units are bridged by pyridyl-based organic linkers, were prepared The crystal structures of 4, 5, 6, 7 and 8 are reported. In the experiment, the researchers used many compounds, for example, 2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7HPLC of Formula: 15420-02-7).
2,5-Di(pyridin-4-yl)-1,3,4-oxadiazole (cas: 15420-02-7) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.HPLC of Formula: 15420-02-7
