چکیده
In the title complex, [Cu2(C8Br4O4)2(C6H16N2)2(H2O)2], the Cu(II) cation is chelated by a tetra-methyl-ethane-1,2-di-amine ligand and coordinated by a water mol-ecule as well as bridged by two tetra-bromo-phthalate anions in a distorted O3N2 trigonal-bipyramidal geometry. The two symmetry-related tetra-bromo-phthalate anions bridge the two Cu(II) cations, forming a centrosymmetric dinuclear complex in which the Cu⋯Cu separation is 5.054 (2) Å. Intra-molecular classic O-H⋯O hydrogen bonds and weak C-H⋯O hydrogen bonds occur in the dinuclear mol-ecule. In the crystal, the mol-ecules are linked by weak C-H⋯Br and C-H⋯O inter-actions into supra-molecular chains propagating along the b-axis direction.

In the two-dimensional title coordination polymer, [Ni(C(8)H(3)BrO(4))(C(14)H(14)N(4))(H(2)O)](n), the Ni(II) atom adopts a distorted octa-hedral geometry, being ligated by three O atoms from two different 5-bromo-benzene-1,3-dicarboxyl-ate ligands, two N atoms from two 1,2-bis-(imidazol-1-ylmeth-yl)benzene ligands and one coordinated water mol-ecule. The Ni atoms are bridged by the 5-bromo-ben...

The full mol-ecule of the binuclear title compound, [Cd2Cl2(C6H8O4)(C6H8N2)2(H2O)2], is generated by the application of a centre of inversion located at the middle of the central CH2-CH2 bond of the adipate dianion; the latter chelates a CdII atom at each end. Along with two carboxyl-ate-O atoms, the CdII ion is coordinated by the two N atoms of the chelating benzene-1,2-di-amine ligand, a Cl- ...

In the title compound, [Cu(C(2)H(3)O(2))(2)(C(6)H(16)N(2))], the Cu(II) atom is coordinated by two N atoms from the chelating N,N,N',N'-tetra-methyl-ethane-1,2-diamine ligand and two O atoms from two acetate anions in a distorted square-planar geometry. In addition, there are longer contacts between Cu and the second O atom of each acetate ligand, which could be considered to complete a distort...

The asymmetric unit of the title compound, [Cu(2)(C(5)H(7)O(2))(4)(C(20)H(16)N(2))], contains half of a centrosymmetric dinuclear mol-ecule. In the mol-ecule, each Cu center is coordinated by four O atoms from two acetyl-acetonate ligands and one N atom from the bridging linear 1,4-bis-[2-(4-pyrid-yl)ethen-yl]benzene ligand in a square-pyramidal geometry. In the crystal structure, weak inter-mo...

In the title coordination polymer, [Zn(C(8)H(4)O(4))(C(14)H(14)N(4))](n), the Zn(II) atom is coordinated by two N atoms from two 1,2-bis-(imidazol-1-ylmeth-yl)benzene ligands as well as by the two O atoms from two terephthalate ligands, confering a tetra-hedral coordination geometry. The bridging ligands generate a three-dimensional structure.
