Unusual {⋯HNC₂O⋯HC_nO}, n = 1 or 2, synthons predominate in the molecular packing of one-dimensional coordination polymers, {Cd[S₂P(OR)₂]₂(³LH₂)}_n, for R = Me and Et, but are precluded when R = i-Pr; ³LH₂ = N,N′-bis(3-pyridylmethyl)oxalamide

Abstract

Linear, one-dimensional coordination polymers, {Cd[S2P(OR)2]2(3LH2)}n, for R = Me (1), Et (2) and i-Pr (3) have been fully characterised by a variety of physiochemical, spectroscopic, crystallographic and computational techniques. Two-dimensional...

“…In particular, N,N'-bis(pyridin-3-ylmethyl)oxalamide (L) was isolated in two polymorphs [11], as a hydrate [12], and it was structurally characterized in about fifteen different cocrystals and about thirty coordination compounds, where the pyridine N-atoms were directly involved in the coordination of transition metal ions as varied as Cu II [13], Zn II [14], Ni II [15], Ag I [16], Au I [17], Co II [18,19], and Pd II [20]. In addition, four Cd II complexes bearing the L oxalamide ligand in combination with carboxylate and dithiophosphato ancillary ligands have been reported to date [18,21].…”
