چکیده
In the title compound, {(NH(4))[Cd(NCS)(3)]·C(12)H(24)O(6)}(n), the Cd(2+) ion, the ammonium cation, one of the SCN(-) ligands and the macrocycle are located on mirror planes. The thiocyanate anions act as bridging ligands between the Cd(II) ions, leading to a polymeric chain arrangement extending along [001] around a twofold screw axis. The ammonium ions are contained within the bowl of the macrocycle via extensive N-H⋯O hydrogen bonding.

In the title compound, [Cd(NCS)(2)(C(11)H(17)N(3))](n), the Cd(II) atom is octa-hedrally coordinated by the N,N',N''-tridentate Schiff base ligand and one terminal thio-cyanate N atom. Two trans-N:S-bridging thio-cyanates complete the N(5)S donor set around the Cd atom. In the crystal, adjacent Cd(II) ions are linked by the thio-cyanate N:S-bridges into polymeric chains along the c axis.

The structure of the title compound, [Cd(NCS)2(C7H9NO)2] n , consists of cadmium-thio-cyanate layers parallel to the ab plane. Pairs of Cd(II) ions are bridged by two end-to-end inversely bridging μ-NCS-N:S thio-cyanate groups, forming a two-dimensional network with the remaining two trans positions of the octa-hedrally coordinated Cd(II) ions occupied by the N atoms of two neutral 2-meth-oxy-a...
