چکیده
The asymmetric unit of the title compound, [Cu(C(9)H(9)O(4))(2)(C(12)H(8)N(2))], contains one half-mol-ecule, the complete mol-ecule being generated by a twofold rotation axis. The Cu(II) atom exhibits a six-coordinated distorted octa-hedral geometry with two N atoms from the phenanthroline ligand [Cu-N 2.007 (2) Å] and four O atoms from two 3,4-dimethoxy-benzoate ligands [Cu-O 1.950 (1) and 2.524 (1) Å]. The difference in Cu-O bond distances indicates a strong Jahn-Teller effect. In the crystal, C-H⋯π inter-actions result in chains of mol-ecules along the c axis.

In the title centrosymmetric dinuclear complex, [Tm(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)], the unique Tm(III) ion is coordin-ated by five 3,4-dimethoxy-phenyl-acetate (DMPA) ligands and and a bis-chelating 1,10-phenanthroline (phen) ligand via seven O atoms and two N atoms, forming a distorted tricapped trigonal-prismatic environment. The DMPA ligands coordin-ate in the bis-chelate, bridging...

The two halves of the title compound, [Cu(C(2)H(2)BrO(2))(2)(C(12)H(8)N(2))], are related by twofold symmetry along the b axis through the central Cu(II) ion. The Cu(II) ion is coordinated by two symmetry-related N atoms from the 1,10-phenanthroline ligand and four O atoms from two 2-bromo-acetate ligands, showing a distorted octahedral geometry. Weak inter-molecular C-H⋯O inter-actions link ne...

In the title compound, [Cu(C(8)H(7)O(2))(2)(C(12)H(8)N(2))], the Cu(II) atom assumes a distorted octa-hedral coordination geometry, chelated by two N atoms from the 1,10'-phenanthroline ligand and four O atoms from two 2-methyl-benzoate anions. A significant Jahn-Teller distortion is observed with two axial Cu-O distances significantly longer than those in the equatorial CuO(2)N(2) plane. In th...

The reaction of cadmium nitrate and sodium nitrite in the presence of 1,10-phenanthroline yields the mixed nitrate-nitrite title complex, [Cd(NO(2))(1.75)(NO(3))(0.25)(C(12)H(8)N(2))(2)]. The metal ion is bis-chelated by two N-heterocycles as well as by the nitrate/nitrite ions in a distorted dodeca-hedral CdN(4)O(4) coordination environment. One nitrite group is ordered; the other is disordere...

In the dimeric centrosymmetric title complex, [Er(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)], the Er(III) ion is nine-coordinated by five 2-(3,4-dimeth-oxy-lphen-yl)acetic acid (DMPA) ligands via seven O atoms and two N atoms from a bis-chelating 1,10-phenanthroline (phen) ligand in a distorted tricapped trigonal-prismatic geometry. The DMPA ligands are coordinated to the Er(III) ion in bis-chela...
