| Popis: | The synthesis and crystal structure of the title compound [systematic name: di-μ-acetato-tetrakis(μ4-N,2-dioxidobenzene-1-carboximidato)hexamethanoltetramanganese(III)nickel(II) methanol disolvate monohydrate], [Mn4Ni(C7H4NO3)4(C2H3O2)2(CH4O)6]·2CH4O·H2O or Ni(OAc)2[12-MCMn(III)N(shi)-4](CH3OH)6·2CH3OH·H2O, where MC is metallacrown, −OAc is acetate, and shi3− is salicylhydroximate, are reported. The macrocyclic metallacrown is positioned on an inversion center located on the NiII ion that resides in the central MC cavity. The macrocycle consists of an MnIII–N–O repeat unit that recurs four times to generate an overall square-shaped molecule. Both the NiII and MnIII ions are six-coordinate with an octahedral geometry. In addition, the MnIII ions possess an elongated Jahn–Teller distortion along the z-axis of the coordination environment. The interstitial water molecule is slightly offset from and disordered about an inversion center. |
