ABSTRACT
In the crystal structure of the title complex, poly[mu-1,4-bis(1,2,4-triazol-1-yl)butane-di-mu-1,5-dicyanamido-cadmium(II)], [Cd(C2N3)2(C8H12N6)]n or [Cd(dca)2(btb)]n, where dca is dicyanamide and btb is 1,4-bis(1,2,4-triazol-1-yl)butane, each Cd(II) atom occupies a center of symmetry and is in a six-coordinated distorted octahedral environment. Four N atoms from four dca ligands fill the equatorial positions, and two N atoms from two btb ligands occupy the axial positions. The dca ligands adopt an end-to-end coordination mode and link the Cd(II) atoms to form a 12-membered Cd(dca)2Cd ring, and neighboring rings extend along the b axis to form a [Cd(dca)2]n chain. The btb ligands, acting as bridging bidentate ligands, link the Cd(II) atoms of adjacent one-dimensional [Cd(dca)2]n chains, forming a rhombic two-dimensional network.
