Aromi, Guillem published the artcileNovel topologies in NiII cluster chemistry: incorporation of alkaline-earth metals in the new [NiII6MgII2] and [NiII8MII] (M = Sr, Ba) cages, Name: 5-Phenyl-1H-pyrazol-3(2H)-one, the main research area is nickel alk earth pivalato pyrazolinone polynuclear complex preparation structure; crystal structure nickel alk earth pivalato pyrazolinone polynuclear complex; magnetic property nickel alk earth pivalato pyrazolinone polynuclear complex.
The reaction of [Ni2(H2O)(piv)4(Hpiv)4] (1) (Hpiv = pivalic acid) with Hppo (3-phenylpyrazolin-5-one) in the presence of a base of an alk.-earth metal (MII = MgII, SrII or BaII) led to three different NiII clusters whose structures are controlled by the nature of MII. The formulas of the new heteronuclear cages are [Ni6Mg2(OH)2(ppo)4(piv)10(Hppo)4(MeOH)2] (2), [Ni8Sr(OH)2(ppo)6(piv)10(Hppo)5(Hpiv)2(MeCN)] (3) and [Ni8Ba(OH)2(ppo)6(piv)10(Hppo)5.3(Hpiv)0.7(MeCN)2] (4). Magnetic measurements indicate that the spin ground state of 2 consists of two independent S = 3 units, while the presence of two noninteracting S = 2 fragments in the mol. is postulated for compounds 3 and 4.
