Bis{?-2,2'-[o-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato}dicopper(II) N,N'-dimethyl-formamide disolvate.

ABSTRACT: The title compound, [Cu(2)(C(20)H(14)N(2)O(2))(2)]·2C(3)H(7)NO, consists of a centrosymmetric dimer composed of two copper(II) ions and two tetra-dentate salphen ligands {H(2)salphen is 2,2'-[o-phenyl-enebis(nitrilo-methyl-idyne)]diphenol}, and two dimethyl-formamide solvent mol-ecules. The Cu(II) atom is bonded to two N imino atoms and three phenolate O atoms of salphen. One deprotonated phenol group of each ligand bridges two Cu atoms, forming the dimer. The geometry about the five-coordinate Cu atom can best be described as slightly distorted recta-ngular pyramidal. The crystal structure is stabilized by ?-? inter-actions [centroid-centroid distance 3.779?(2)?Å] and C-H?O hydrogen bonds.

Bis{?-4,4'-dibromo-2,2'-[o-phenyl-enebis(nitrilo-methyl-idyne)]diphenolato}bis-[chloridomanganese(III)] N,N-dimethyl-formamide disolvate.

Project description:The asymmetric unit of the title compound, [Mn(2)(C(20)H(12)Br(2)N(2)O(2))(2)Cl(2)]·2C(3)H(7)NO, contains one half of a centrosymmetric dinuclear Mn(III) complex and an N,N-dimethyl-formamide solvent mol-ecule. In the complex, the two Mn(III) ions are bridged by two O atoms from two symmetry-related N,N'-bis-(5-bromo-salicyl-idene)-1,2-diimino-benzene dianionic ligands with the longer Mn-O distance of 2.703?(3)?Å, thus each Mn ion is six-coordinated by two N and three O atoms from the two dianionic ligands and one capping Cl atom in a distorted octa-hedral environment. The crystal structure displays inter-molecular ?-? inter-actions between adjacent benzene rings, with a shortest centroid-centroid distance of 3.673?(2)?Å, and inter-molecular C-H?O, C-H? Cl and C-H? Br hydrogen bonds.

Project description:The title compound, [Co(C(22)H(18)N(2)O(4))]·2CH(2)Cl(2), was isolated from the reaction of N,N'(o-phenyl-ene)bis-(vanillalimine) (H(2)L) with Co(SCN)(2). The crystal structure contains a Co(II) ion surrounded by the L(2-) ligand in a slightly distorted square-planar fashion. Inter-molecular C-H?O hydrogen-bonding contacts between the dichloro-methane solvent mol-ecules and the meth-oxy or carboxyl-ate O atoms are observed in the crystal structure. The planar complex mol-ecules stack through inversion related ?-? inter-actions between the six-membered rings of the vanillalimine half ligands. The distance between centroids is 3.498?(2)?Å and the perpendicular distance is 3.345?Å. A partial stacking is observed with a centroid-centroid distance of 3.830?(2)?Å, a perpendicular distance of 3.350?Å and a slippage of 1.856?Å.
