چکیده
The heterometallic title complex, [Cr(2)Mn(2)(C(5)H(11)NO(2))(2)(C(5)H(12)NO(2))(2)(NCS)(4)]·4C(3)H(7)NO, was prepared using manganese powder, Reineckes salt, ammonium thio-cyanate and a non-aqueous solution of N-methyl-diethano-lamine in air. The centrosymmetric mol-ecular structure of the complex is based on a tetra-nuclear {Mn(2)Cr(2)(μ-O)(6)} core. The tetra-nuclear complex mol-ecule and the two uncoordinated dimethyl-formamide mol-ecules are linked by O-H⋯O hydrogen bonds, while the two other mol-ecules of dimethyl-formamide do not participate in hydrogen bonding.

The tetra-nuclear complex cation of the title compound, [Cr2Pb2(NCS)2(OH)2(C4H10NO)4](SCN)2·CH3CN, lies on an inversion centre. The main structural feature of the cation is a distorted seco-norcubane Pb2Cr2O6 cage with a central four-membered Cr2O2 ring. The Cr(III) ion is coordinated in a distorted octa-hedron, which involves two N atoms of one bidentate ligand and one thio-cyanate anion, two ...

The complex mol-ecule of the title compound, [Ni(4)(C(4)H(10)NO(2))(4)Cl(4)]·CH(3)OH, consists of a cubane-like {Ni(4)O(4)} core in which each nickel(II) atom is six-coordinated in a distorted octa-hedral geometry by one N and four O atoms of three mono-deprotonated diethano-lamine ligands and by a chloride anion. The mol-ecular conformation is stabilized by intra-molecular O-H⋯Cl bonds. In the...

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,...
