“…The shortest CuÁÁÁCc distances of 3.01 and 3.06 Å were found in trans-Cu(benzoylacetonato) 2 [81] and Cu(acac) 2 , respectively [82]. In these two compounds centroid-centroid contacts are 3.13 and 3.14 Å with the angle between metallacycles being 0.02°.…”

“…Metal complexes of b-diketonate ligands are of interest in solid-state supramolecular chemistry mostly owing to their promise as building blocks for the design of porous and supramolecular materials with interesting electronic, magnetic, and optical properties [1][2][3][4]. Furthermore, metal complexes of b-diketonate derivatives can be good precursors in metal-organic chemical vapour deposition (MOCVD) [5].…”

“…Control of the solid-state arrangement of molecules within a crystal is a central challenge in materials chemistry and the control of coordination chemistry is essential in inorganic crystal engineering [6]. The b-diketonates are suitable for incorporation into metallosupramolecular structures [1,2]. They can be easily derivatized, thus modifying the electronic and steric nature of these ligands and allowing one to design suitable structure-function relationships.…”

“…Interestingly, when Cu(acac) 2 interacts with an additional ligand, a five coordination is predominant. Only two crystal structures are known with octahedral coordination of copper in Cu(acac) 2 (L) 2 [7,8]. The presence of additional electron-withdrawing fluorine atoms on b-diketonato ligands enhances the acidic character of the central copper atom and octahedral coordination can be easily achieved [1,[9][10][11].…”

Different coordination modes and supramolecular aggregations in copper(II) pentane-2,4-dionato compounds with 2-pyridone and 3-hydroxypyridine

Copper(II) bis(pentane-2,4-dionato-j 2 O,O 0 ) compounds with 2-pyridone (1) and 3-hydroxypyridine (2) were prepared by the reaction of bis(pentane-2,4-dionato-j 2 O,O 0 ) copper(II) with selected ligands. The coordination of Cu(II) in both compounds is square pyramidal with the fifth coordination site occupied by the carbonyl oxygen atom of the 2-pyridone ligand in 1 and by the nitrogen atom of 3-hydroxypyridine in 2. The X-ray crystallographic studies revealed different crystal aggregation influenced by the ability of the 2-pyridone ligand to act as a hydrogen bond donor and acceptor, and 3-hydroxypyridine acting only as a hydrogen bond donor. Intermolecular N-HÁÁÁO hydrogen bonding forms dimers in 1 and infinite chains in 2. Three-dimensional aggregation is achieved by p-p interactions and C-HÁÁÁp (arene) hydrogen bonding.

“…Recently, there has been growing interest in the design of metalloligands for use as small structural units in selfassembly reactions to produce larger supramolecular entities [15][16][17][18][19][20][21]. Such metalloligands include examples of mononuclear tripodal ligand complexes whose secondary (uncoordinated) donor sites are respectively pyridine [22] and imidazolate [23] nitrogens, with the latter suitably positioned at the terminus of each arm of its tripodal complex This paper is dedicated to Professor Jack Harrowfield and Dr. Jacques Vicens in commemoration of their 70th birthdays.…”

The in situ Schiff base condensation of 2-acetylpyrazine with tris(2-aminoethyl)amine in the presence of zinc(II) perchlorate was carried out in absolute ethanol and 95 % ethanol, respectively. Two new tripodal metalloligands, 1 and 2, were isolated. The formation of complexes 1 and 2 has been verified by NMR, mass spectral studies and X-ray (for 2), with the evidence indicating that a zinc ion is incorporated in the tripodal cavity defined by the tren backbone in each case. However the products differed in the number of Schiff base condensation reactions that had occurred. While the use of absolute ethanol resulted in condensation at all three primary amine sites of tris(2-aminoethyl)amine, employing 95 % ethanol yielded condensation at only one of the primary amine sites. These different outcomes can be ascribed, at least in part, to the effect of the different water contents in the respective reaction solvents resulting in a shift of the dynamic equilibrium involving imine formation towards the precursor amine and ketone reagents. In 1, steric considerations dictate that the three uncoordinated pyrazine nitrogen donors will have their coordination vectors oriented in a mutually divergent manner suitable for coordination to three different metal centres when acting as a metalloligand while for 2, the X-ray structure confirms that the single uncoordinated (pendent) pyrazine nitrogen is also oriented for ready coordination to a second metal centre.

There has been growing interest in coordination chemistry, particularly in the field of porous metal–organic frameworks (MOFs). Since the functionalities of MOFs can be systematically tuned by integrating functional groups in their frameworks, MOF materials have been realized applications in a number of fields, including luminescence, gas storage, sensing, magnetics, and catalysis. Because porphyrins and metalloporphyrins have rigid structures and remarkable functionalities of catalysis, charge, and energy transformations, they have been used as functional building blocks to fabricate porphyrinic MOFs for applications in various fields. This chapter is focused on recent progress on the emerging functional materials, including synthetic strategies and applications of porphyrinic MOFs.
