“…A characteristic band due to CN stretching of HMTA was observed at 1227-1244 cm À1 as expected [51]. The v(CO) vibrations of the mononuclear complexes were not significantly different from those of the dinuclear complexes and therefore it was not possible to distinguish the mononuclear from the dinuclear…”

“…Taking into consideration only the metal-hmt interactions, two types of topologies were identified (Scheme 3), namely the honeycomb-like hexagons in [Cd 3 Br 6 ( 3 -hmt) 2 (H 2 O) 5 ] n ·n(hmt)·6nH 2 O (38) [12], [Cd 3 (ac) 6 ( 3 -hmt) 2 (H 2 O) 3 ] n ·6nH 2 O (40) [10] and [Cu 3 ( 2 -pbpd) 3 ( 3 -hmt)] n (35) [24], and the periodically tiled pentagons in [Cu 2 ( 2 -prop) 4 ( 4 -hmt)( 3 -hmt) 2 ] n (34) [41].…”

“…Compounds 38 and 40 feature the almost regular hexagon rings that are constructed from six 3 -hmt linkers and six monocadmium nodes (for typical example, see [12], while only one type of the node, [Cd(ac) 2 (H 2 O)], is observed in 40 [10]. The copper(II) polymer 35 [24] is built from the fused chiral hexagons [(Cu 2 ) 6 (hmt) 6 (pbpd) 12 ] that possess a very distorted topology.…”

“…The copper(II) polymer 35 [24] is built from the fused chiral hexagons [(Cu 2 ) 6 (hmt) 6 (pbpd) 12 ] that possess a very distorted topology. The infinite 2D layers of 38, 40 and 35 are undulating and thus exhibit the bent honeycomb-like topologies.…”

“…The analysis of these interactions led to the identification of various water associates (see section 6.1) trapped within the host 2D metal-organic matrices of coordination polymers. Besides, the structure of 38 also bears the uncoordinated guest molecules of hmt, each of them acts as an acceptor of four H-bonds, thus providing a 3D supramolecular network [12].…”

The reaction of cadmium(II) acetate salts with multisite coordinated compartmental Schiff base ligand N,N'-Bis(3methoxysalicylidenimino)-1,3-diaminopropane (H 2 L 1 ) in presence of co-lingand azido/thiocyanato afforded two new coordination polymers {[Cd 4 (N 3 ) 4 (L 1 ) 2 ]·H 2 O} n (1), [Cd 4 (SCN) 4 (L 1 ) 2 ] n (2). The obtained compounds, 1 and 2 are 1D and 2D coordination polymers respectively and they have been characterized by IR spectroscopy, UV-vis spectroscopy, elemental analysis, and single-crystal X-ray diffraction. The variation in the extended forms of 1 and 2 is governed by the kind of coligands utilized in the reaction. The complete structural study reveals that, in both cases the fully deprotonated ligand [L 1 ] 2À has utilized all six potential coordination sites to hold a pair of Cd(II) ions. Moreover, [N 3 ] À in 1 is coordinating to metal atom by both trans end-to-end (EE m-1,3) and end-on (EO or m-1,1) mode and [SCN] À is showing only end-to-end (EE m-1,3) coordination mode in 2. The photo luminescent properties and antimicrobial activities of the compounds 1 and 2 were investigated and discussed in details. Upon irradiation with UV light Cd(II) polymeric compounds 1-2 exhibit deep blue emissions of 448 À 451 nm subjected to dimethyl sulfoxide solution due to p!p* intraligand fluorescence. Apart from, as a complementary revelation, intermolecular interactions with respect to percentages of hydrogen bonding in the crystal structures of two Cd(II) polymeric compounds were quantified by Hirshfeld surface and fingerprint plots analysis.
