چکیده
The title compound, [Cu(4)Br(4)(C(21)H(22)Br(2)N(4))(4)], features a macrocyclic Cu(4)L(4) ring system in which each Cu(I) atom is coordinated by one bromide ion and two N atoms from two 2,2'-dimethyl-1,1'-[2,2-bis-(bromo-meth-yl)propane-1,3-di-yl]di(1H-benzimidazole) (L) ligands in a distorted trigonal-planar geometry. The L ligands adopt either a cis or trans configuration. The asymmetric unit contains one half-mol-ecule with the center of the macrocycle located on a crystallographic center of inversion. Each bromide ion binds to a Cu(I) atom in a terminal mode and is oriented outside the ring. The macrocycles are inter-connected into a two-dimensional network by π-π inter-actions between benzimid-azole groups from different rings [centroid-centroid distance = 3.803 (5) Å.

The complete mol-ecule of the title complex, [Co(2)(C(8)H(7)O(3))(4)(C(20)H(22)N(4)O)(2)], is a dimer of the paddle-wheel-type generated by crystallographic inversion symmetry. The Co(II) ion is penta-coordinated by three O atoms from two 4-meth-oxy-benzoate anions (one bidentate and one monodentate) and two N atoms from two 2,2'-bis-(2-methyl-1H-benzimidazole)-ether ligands. This results in a ...
