• Hydrogen bonding in organometallic and metal-organic crystals. Transition metal amido complexes

• Assembling one-dimensional coordination polymers into threedimensional architectures via hydrogen bonds

The reactions of bis(pyridylcarboxamido)alkanes (amides) and bis(3-pyridyl)alkanediamides (reverse amides) with copper(II) and zinc(II) in the presence of various anions resulted in onedimensional polymeric crystalline complexes with or without guest inclusion. The crystal structure analyses of these complexes reveal that the one-dimensional networks observed here are of three types: simple linear chain, chains with wavy nature and chains containing cavities. The self-complementary amide groups of the ligands assembled these coordination networks into higher dimensional architectures via N-H$\cdots$O hydrogen bonds.

• 3D, 2D and 1D networks via N-H…O and N-H…N hydrogen bonding by the bis-amide analogues: Effect of chain lengths and odd-even spacers

The synthesis, crystal structures and hydrogen bonding networks of four members of the bis(pyridinecarboxamido)alkane and bis(pyridyl)alkanediamides series (1 ≤ 𝑛 ≤ 8), where the amide moieties are separated by alkyl chain (-(CH2)$_n$-) having even or odd number of -(CH2)-groups are explored and correlated with the previously reported structures. The odd members (n= odd) of both the series are found to adopt three-dimensional networks in contrast to the 1D or 2D structures of the even members (n= even). This odd-even effect on the dimensionality of the networks however disappears with increase in chain length.
