چکیده
The title compound, [Li(2)(C(18)H(22)BO)(2)(C(6)H(7)N)(2)], is a lithium dimesitylboroxide dimer in which the lithium cation is also coordinated by one mol-ecule of 2-methyl-pyridine. At the core of the structure is an Li(2)O(2) four-membered ring. The structure is centrosymmetric with an inversion centre midway between two Li atoms. Inter-molecular C-H⋯π inter-actions and π-π inter-actions between the 2-methyl-pyridine rings exist [centroid-centroid distance = 3.6312 (16) Å].

The binuclear title complex, [Zn2(C33H33N6O)(CH3COO2)(CH3OH)](ClO4)2, was synthesized by the reaction between 2,6-bis-({[bis-(pyridin-2-yl)meth-yl]amino}-meth-yl)-4-methyl-phenol (H-BPMP), Zn(OAc)2 and NaClO4. The two Zn(II) ions are bridged by the phenolate O atom of the octadentate ligand and the acetate group. An additional methanol ligand is terminally coordinated to one of the Zn(II) ions,...

The title compound, [Mn2(C7H4NO4)4(C6H7N)4] or [Mn2(μ-NBz)2(κ2-NBz)2(4-Mepy)4], where NBz is 4-nitro-benzoate and 4-Mepy is 4-methyl-pyridine, is a centrosymmetric dinuclear complex in which the MnII atoms are bridged by two NBz ligands with Mn⋯Mn = 4.1324 (4) Å. The MnII atom in this dimeric species is present in a distorted octa-hedral environment with the four coordinating O atoms forming th...
متن کاملTetrakis(μ-pivalato-κ2 O:O′)bis[(2-methylpyridine-κN)iron(II)](Fe—Fe)
The asymmetric unit of the title compound, [Fe(2)(C(5)H(9)O(2))(4)(C(6)H(7)N)(2)], contains one unique Fe-atom site located close to a centre of symmetry which generates the mol-ecular dimer. The two Fe atoms are bridged by four carboxyl-ate groups and are each coordinated by a mol-ecule of 2-picoline. Electron counting and the 18-electron rule suggest that a chemical single bond is likely to e...

The title tetra-nuclear Cu(II) complex, [Cu(4)(C(12)H(12)N(2)O(2))(4)(CH(3)O)(4)(ClO(4))(2)](ClO(4))(2), is located around an inversion center. Each Cu(II) atom is coordinated by two cis-O atoms from two bridging methano-late anions and two cis-N atoms from two bridging 1,4-bis-(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in the basal plane, and is further coordinated by one O atom of the b...

In the binuclear title compound, [Cu(2)(NO(2))(4)(C(4)H(6)N(2))(4)], centro-symmetric-ally related complex mol-ecules are linked via weak Cu-O inter-actions, forming dimeric units. The Cu(II) atom displays an elongated square-pyramidal CuN(2)O(3) coordination geometry with a slight tetra-hedral distortion of the basal plane [maximum deviation = 0.249 (2) Å]. The dihedral angle formed by the imi...
