چکیده
The dinuclear compound, [V(2)(C(12)H(11)BrN(2)O(2))(2)(CH(3)O)(2)O(2)], lies on a center of inversion. The doubly-deprotonated Schiff base O,N,O'-chelates to the V(V) atom; two metal atoms are bridged by the methoxide units. The coordination geometry is a distorted octa-hedron. Weak inter-molecular C-H⋯N hydrogen bonding is present in the crystal structure. The bromo-phenyl unit is disordered over two positions, with the major component being in a 0.909 (6) proportion.

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...
