2. Syntheses and crystal structures of two new coordination polymers of Cd(II) using organic spacer and inorganic-bridging ligands.
- Abstract
Two new cadmium (II) complexes [Cd(hmt)(dca)
2 ]n (1) and [Cd3 (hmt)2 (SeCN)6 (H2 O)2 ]n (2) (hmt=hexamethylenetetramine, dca=dicyanamide) have been synthesized and characterized by X-ray single-crystal analysis. The complex 1 is a 2D rectangular grid of octahedral cadmium (II) with CdN6 chromophore where cadmium centers are doubly bridged by dicyanamide and hmt along a-axis, which are interlinked by dicyanamide running along c-axis. Whereas, complex 2 is a 1D chain of octahedral cadmium (II) with a three-leg ladder topology running along a-axis. The Cd(II) centers are doubly bridged through SeCN (infinite rail) along a-axis and singly bridged by hmt (two-step rung) along c-axis, having cadmium centers with CdSe2 N3 O and CdSe2 N4 chromophores. The adjacent chains through H-bonding between coordinated water and hmt, and Se!["$$\cdots$$"]("/fulltext-image.asp?format=htmlnonpaginated&src=E0M544581W280036_html\11224_2006_9017_Article_IEq1.gif")
