چکیده
In the title compound, [Mg(C3H2O4)(H2O)3] n , the metal atom is in an octa-hedral environment. The octa-hedra are connected by malonate anions, forming chains along the c-axis direction. O-H⋯O hydrogen bonds link these chains into a three-dimensional network.

In the title compound, [Ag(2)(C(2)N(3))(2)(C(10)H(8)N(2))](n), the Ag atoms, lying on inversion centers, are separated by 3.3226 (12) Å. Each Ag atom is connected by one bridging 4,4'-bipyridine [Ag-N = 2.177 (4)Å] and a terminal dicyanamide [Ag-N = 2.108 (4) Å]. The Ag-Ag interactions play a key role in constructing a unique neutral polymeric chain.

The reaction of CdCl(2), 18-crown-6 and KI in water yields the title coordination polymer, [{K(C(12)H(24)O(6))}(2)Cd(2)I(6)](n). The potassium ion lies approximately in the plane of the crown ether, coordinated by all six crown ether O atoms and also by an iodide anion bound to a cadmium atom. A C atom of the crown ether is disordered over two positions with site occupancies of 0.77 (2) and 0.2...

The structure of the title compound, [Cd(3)Cl(6)(C(15)H(15)NO(2))(2)(CH(4)O)(2)](n), is based on a layered zigzag polymeric chain along the c axis. The Cd(II) ions are linked by double chlorine bridges alternating between one CdCl(4)(CH(3)OH)(2) and two CdCl(4)(C(15)H(15)NO(2)) octa-hedral coordination units. Additional intrachain N-H⋯O and O-H⋯Cl hydrogen-bond interactions stabilize this arran...
