The core of the molecule consists of two metallacrown (MC) rings, an archetypal 12-MC-4 and a collapsed 11-MC-4, that are linked through a common ring Dy<sup>III</sup> center. For the 12-MC-4 portion of <b>1</b>, the heterobimetallic composition of the MC ring with one Dy<sup>III</sup> and three Mn<sup>III</sup> ions is uncommon for metallacrowns as most 12-MC-4 rings are homometallic. In addition, the 12-MC-4 binds a Dy<sup>III</sup> cation in the central cavity of the MC. The coordination environment about the central Dy<sup>III</sup> ion has a triangular dodecahedron shape, which again is atypical. For 12-MC-4 molecules with a central lanthanide ion, the central lanthanide ion typically adopts a square antiprism geometry. The ring Dy<sup>III</sup> cation of the 12-MC-4, which has a biaugmented trigonal prism shape, is shared with the collapsed 11-MC-4 and serves to join both metallacrowns. The collapsed 11-MC-4 ring is also composed of three Mn<sup>III</sup> and one Dy<sup>III</sup> ions. For one of the ring metal–metal linkages, only an oxygen atom is present, and an eleven membered ring is generated. In addition, the Dy<sup>III</sup> center and one of the Mn<sup>III</sup> centers bind to ring oxygen atoms on the opposite side of the MC ring; thus, the potential cavity of the MC is collapsed, and the MC does not bind a central metal ion as is customary.</p><h3>Graphical Abstract</h3>\u0000 <figure><div><div><div><picture><source><img></source></picture></div></div></div></figure>\u0000 </div>","PeriodicalId":615,"journal":{"name":"Journal of Chemical Crystallography","volume":"53 2","pages":"307 - 320"},"PeriodicalIF":0.8,"publicationDate":"2022-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4512180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dihedral angle between the thiophene and cyclohexyl rings is 60.7(4)<sup>°</sup>. The crystal packing is established by intermolecular N–H⋯O packing interactions involving a three-center donor hydrogen bond between the keto oxygen atom of the thiophene group and H atoms belonging to the hydrazine group which links the molecules into chains along the (011) plane of the unit cell.

Intermolecular interactions are based mainly on a moderate N–H⋯O and O–H⋯O hydrogen bonds. The structure shares similar structural features with other structures containing aspartates and their derivatives as a ligands. The results of using different HAR methods based on semi-empirical (B3LYP) and non-empirical (PBE0) global hybrid GGA DFT functionals were compared.</p><h3>Graphical Abstract</h3><p>The crystal structure of NH<sub>4</sub>[Zn(<i>cma</i>)(H<sub>2</sub>O)<sub>2</sub>]·H<sub>2</sub>O (<i>cma</i><sup>3–</sup> = N-carboxymethylaspartate(3–)) is determined by single crystal X-ray structure analysis.

In both case N-heterocyclic ligands are distorted towards palladium direction. Further, crystal structures reveal that the palladium atom is covalently bonded to the two aNHC and nNHC ligands respectively. The electrochemical properties of these complexes were determined by cyclic voltammetry analysis in THF solution under argon atmosphere. The enunciated reversibility of the complexes can be explained by sequential one electron oxidations of the palladium centre from Pd(0) to Pd(I) and then Pd(II).</p><h3>Graphical Abstract</h3><p>Abnormal carbene complex of Pd(L1)<sub>2</sub>, where L1 = 1,3-Bis(2,6-diisopropylphenyl)-2,4-diphenylimidazole and normal carbene complex of Pd(L2)<sub>2</sub>, where L2 = 1,3-dimesityl-4,9-dioxonaphtho-2,3-diimidazole were prepared from a Pd(0) precursor of Pd(COD)(CH<sub>2</sub>TMS)<sub>2</sub>.
