The chemical preparation, crystal structure and spectroscopic characterization of two new Cu(II) complexes [Cu(ampymo)4](O2CMe)2, ( 1 ) and [Cu(C5H7N3O)2(H2O)3](CH3COO)2, [Cu(ampymo)2(H2O)3](O2CMe)2, ( 2 ) with the monodentate ligand 2-amino-6-methylpyrimidin-4-(1H)-one, (ampymo), are reported. In ( 1 ), the Cu(II) atom is four-coordinated, in a square planar fashion, by nitrogen atoms of four ampymo ligands. In ( 2 ), it is five-coordinated in a square pyramidal fashion by two pyrimidine nitrogen atoms and three water oxygen atoms. The crystal structure of ( 1 ) is stabilized by N H⋯O hydrogen bonds with pillars of the cationic complexes alternating with channels occupied by the acetate anions. In the atomic arrangement of ( 2 ), the complex cations are located parallel to the (a, b) plane between which the acetate anions intercalate by establishing hydrogen bonds with these cations to form a tridimensional network. The vibrational absorption bands were identified by infrared spect...

Use of Hirshfeld surfaces calculated from crystal structure determinations on various transition metal ion complexes of three terpyridine ligands carrying trimethoxyphenyl substituents has enabled an assessment of the contribution made by the ligand components to the interactions determining the lattice structures, interactions expected also to be present in metallomesogens derived from similar ligands. The form of the link joining the trimethoxyphenyl substituent to the 4' position of…

Two new coordination compounds {(bpyH 2)·[Fe(bpy) 2 (H 2 O) 2 (SO 4) 2 ]·2(H 2 O)} n (1) and {[Cu(bpp) 2 (H 2 O)]·(BF 4) 2 ·dmf·0.75(H 2 O)} n (2), (where, bpy= 4,4'-bipyridine and bpp= 1,3-bis(4-pyridyl)propane, dmf= N,N-dimethylformamide) have been synthesized by slow evaporation method based on rigid and flexible bis(pyridine) ligands. The obtained compounds were characterized by thermal analysis, FT-IR spectroscopy and single crystal X-ray diffraction analysis. The structure of 1 is a channel-containing open framework constructed through the hydrogen-bonding supported by the criss-cross arrangement of the 1D Fe-bpy anionic chains, in which the surrounding of the metal atom is completed by oxygen atoms belonging to water molecules and SO 4 2-anions. The structure of 2 is formed by a one-dimensional polymeric cationic chain, in which the four bpp ligands connect with Cu(II) by four nitrogen atoms and one oxygen atom that belongs to a molecule of water that completes the surrounding of each metal atom. The complexes crystallize in the monoclinic space groups C2/c and P2 1 respectively, where Fe(II) and Cu(II) ions present a N 2 O 4 octahedral and N 4 O square pyramidal environment. The hydrophilic regions absorb bpyH 2 2+ and water molecules in 1 and BF 4-anions, water and dmf molecules in 2, which are held in the crystal lattices via hydrogen bonds.

Analysis of the weak interactions within the crystal structures of 33 complexes of various 4′-aromatic derivatives of 2,2′:6′,2″-terpyridine (tpy) shows that interactions that exceed dispersion are dominated, as expected, by cation⋯anion contacts but are associated with both ligand–ligand and ligand–solvent contacts, sometimes multicentred, in generally complicated arrays, probably largely determined by dispersion interactions between stacked aromatic units. With V(V) as the coordinating cation, there is evidence that the polarisation of the ligand results in an interaction exceeding dispersion at a carbon bound to nitrogen with oxygen or fluorine, an interaction unseen in the structures of M(II) (M = Fe, Co, Ni, Cu, Zn, Ru and Cd) complexes, except when 1,2,3-trimethoxyphenyl substituents are present in the 4′-tpy.
