{Reference Type}: Journal Article {Title}: Triaceto-nitrile-(1,4,7-trimethyl-1,4,7-tri-aza-cyclonona-ne)cobalt(II) bis-(tetra-phenyl-borate). {Author}: Shin J;Kim J;Choi J; {Journal}: IUCrdata {Volume}: 9 {Issue}: 0 {Year}: 2024 Jun 暂无{DOI}: 10.1107/S241431462400539X {Abstract}: The title cobalt(II) complex, [Co(C2H3N)3(C9H21N3)](C24H20B)2 or [(tacn)Co(NCMe)3][BPh4]2, has been characterized by single-crystal X-ray diffraction. It incorporates the well-known macrocyclic tacn (1,4,7-trimethyl-1,4,7-tri-aza-cyclo-nona-ne) ligand, which is coordinated facially to the metal center. The complex crystallizes in space group P21/c with Z = 4. The divalent cobalt ion exhibits a six-coordinate octa-hedral geometry by one tacn and three aceto-nitrile ligands. Two non-coordinating tetra-phenyl-borate (BPh4 -) anions are also present.
