چکیده

The asymmetric unit of the title compound, [Li(4)(C(5)H(3)N(2)O(2))(4)(H(2)O)(4)], contains two symmetry-independent Li(I) ions, two symmetry-independent ligands and two symmetry-independent coordinated water mol-ecules. They form a dinuclear unit in which the two Li(I) ions are bridged by two carboxyl-ate O atoms from the two ligands. Two dinuclear units related by an inversion centre form the tetra-meric mol-ecule. One of the Li(I) ions shows a distorted tetra-hedral coordination geometry, the other a distorted trigonal-bipyramidal environment. The tetra-mers are held together by hydrogen bonds in which coordinated water mol-ecules act as donors, and the carboxyl-ate O atoms act as acceptors. A hydrogen bond between coordinated water molecule as donor and a ring N atom as acceptor is also observed.

In the title compound, [Cu(3)(C(5)H(3)N(2)O(2))(2)(N(3))(4)](n), one of the Cu(II) atoms lies on an inversion centre and is octa-hedrally coordinated by two bidentate chelating pyrimidine-2-carboxyl-ate ligands and two azide anions, each of which gives an N:N-bridge to the second inversion-related Cu(II) centre in the formula unit. The second Cu(II) atom is five-coordinated with a distorted squ...
