CCDC no.: 1565197The asymmetric unit of the title crystal structure is shown in the figure. Tables 1 and 2 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters. (18.4 mg, 0.1 mmol) in 3 mL MeCN with stirring. The resulting mixture was placed in the dark, and red crystals were obtained after two weeks, in a yield of 46% (based on Co). Source of materials Experimental detailsHydrogen atoms potentially involved in hydrogen-bonding interactions were located by difference methods and their positional and isotropic displacement parameters were refined. Other H atoms were included in the refinement at calculated positions [C-H aromatic = 0.93 Å] and treated as riding models with U iso (H) = 1.2Ueq(C). CommentThe bis(2-pyridyl)ketone and its derivative di(pyridin-2-yl)methanediol (H 2 L), and the anionic HL − have been widely used as multidentate and chelating ligands to exhibit a variety of coordination modes [3][4][5][6][7][8].The title structure is made up of cations of [Co(HL) 2 ], one perchlorate anion and two water molecules. The central metal Co(III) ion is sixfold coordinated by two oxygen atoms and four nitrogen atoms from two HL − . The cation of the title complex is similar in structure to a Fe(III) complex of tridentate HL − ligand [9]. In title complex, the bond lengths of Co-O are 1.8862(12) Å and 1.8908(12) Å, and the Co-N bond distances are in the range of 1.9141(16)-1.9309(15) Å, which are comparable to other Co(III) complexes [10,11]. In the crystal structure, the cations are interlinked by hydrogen bonds and π-π interactions to form a 3D supramolecular structure.

Abstract:The combined use of di-2-pyridyl ketone, (py) 2 CO, and acetates (MeCO 2´) in nickel(II) chemistry in H 2 O-MeCN under basic conditions (Et 3 N) afforded the coordination cluster [Ni 11 (OH) 6 (O 2 CMe) 12 {(py) 2 C(OH)(O)} 4 (H 2 O) 2 ] (1) in 80% yield, where (py) 2 C(OH)(O)´is the monoanion of the gem-diol form of (py) 2 CO. The complex contains a novel core topology. The core of 1 comprises a central non-linear {Ni 3 (µ 2 -OH) 4 } 2+ subunit which is connected to two cubane {Ni 4 (OH)(µ 3 -OR) 2 (µ 3 -OR 1 )} 4+ subunits [RO´= (py) 2 C(OH)(O)´and R 1 O´= MeCO 2´] via the OHǵ roups of the former which become µ 3 . The linkage of the Ni 3 subunit to each Ni 4 subunit is completed by two η 1 :η 1 :µ 2 and one η 1 :η 3 :µ 4 MeCO 2´g roups. Peripheral ligation is provided by two terminal monodentate MeCO 2´a nd two terminal aqua ligands. The (py) 2 C(OH)(O)´ligands adopt the η 1 :η 1 :η 3 :µ 3 coordination mode. From the twelve MeCO 2´l igands, two are η 1 , two η 1 :η 3 :µ 4 and eight adopt the syn, syn η 1 :η 1 :µ 2 coordination mode; four of the latter bridge Ni II centers at opposite faces of the cubane subunits. Complex 1 is the largest nickel(II)/(py) 2 CO-based ligand coordination cluster discovered to date and has an extremely rare nuclearity (Ni 11 ) in the cluster chemistry of nickel(II). Variable-temperature, solid state dc susceptibility, and variable-field magnetization studies at low temperatures were carried out on complex 1. The study of the data reveals an S = 3 ground state, which has been well rationalized in terms of known magnetostructural correlations and the structural features of 1. An attempt has also been made to interpret the magnetic properties of the undecanuclear cluster in a quantitative manner using four exchange interaction parameters and the obtained J values are discussed. The role of H 2 O in the solvent medium that led to 1, and the high nickel(II) and acetate to di-2-pyridyl ketone reaction ratio employed for its preparation, on the nuclearity and identity of the cluster are critically analyzed.
