Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 28903-71-1, is researched, SMILESS is COC1=CC=C(C=C1)C(C2=[N]3[Co+2]4([N-]56)[N-]7C(C(C8=CC=C(C=C8)OC)=C3C=C2)=CC=C7C(C9=CC=C(C=C9)OC)=C%10C=CC%11=[N]4%10)=C5C=CC6=C%11C%12=CC=C(C=C%12)OC, Molecular C48H38CoN4O4Journal, Inorganica Chimica Acta called Effect of N,N,N’-trimethylpiperazinium (TMP+) cations on magnetic properties and dimerization of fullerenes in the (TMP+)(CoIIporphyrin)(C-60) salts, Author is Konarev, Dmitri V.; Khasanov, Salavat S.; Lyubovskaya, Rimma N., the main research direction is trimethylpiperazinium cobalt porphyrinato complex fullerene anion preparation crystal structure; magnetism trimethylpiperazinium cobalt porphyrinato complex fullerene anion.Formula: C48H38CoN4O4.
New salts of fullerene C•-60 radical anions with N,N,N’-trimethylpiperazinium cations (TMP+) containing neutral cobalt(II) porphyrin mols.: {(TMP+)·CoIIOEP}·(C•-60)·2C6H4Cl2·C6H5CN (1) and (TMP+)3{CoIITMPP·(C-60)}2(C•-60) ·C6H4Cl2·C6H5CN (2) were obtained (OEP and TMPP are octaethyl- or tetrakis(4-methoxyphenyl)porphyrins, resp.). In these salts the C•-60 radical anions or the TMP+ cations with free nitrogen atom can coordinate to cobalt(II) porphyrins and form Co-C(C-60) or Co-N(TMP+) bonds. The properties of these salts and the possibility of fullerene dimerization depend on type of bonds formed. For example, TMP+ cations in 1 form coordination (TMP+)·CoIIOEP assemblies preserving free nonbonded C•-60 radical anions. They are effectively coupled with S = 1/2 spins localized on CoIIOEP (Weiss temperature is -27 K and decrease of magnetic moment of 1 is observed <150 K). Previously the {(MDABCO+)·CoIITMPP}2·(C-60)2·(C6H4Cl2)2.5·(C6H5CN)1.5 salt was obtained in which doubly-bonded (C-60)2 dimers were found. In contrast to this salt, TMP+ cations in 2 preserved uncoordinated allowing the formation of the Co-C(C-60) bond of 2.273(3) Å length in the diamagnetic σ-bonded CoIITMPP·(C-60) anions. In coordinated state, fullerene anions cannot dimerize in 2 in spite of that their mutual arrangement and short interfullerene distances are favorable for such dimerization. Thus, variation of cations in the (Cation+)(CoIIporphytin)(C-60) salts drastically affects their properties and allows one to control dimerization of fullerene anions.
