“…The hydrogen atom, H(21C), attached to the carbon atom, C(21), is involved in intermolecular C–H···π interaction with the naphthalene ring, Cg(14) [C(41)–C(42)–C(43)–C(44)–C(45)–C(46)]. The naphthalene rings Cg(9) [C(1)–C(2)–C(3)–C(4)–C(9)–C(10)] and Cg(13) [C(37)–C(38)–C(39)–C(40)–C(41)–C(46)] are involved in intermolecular π···π interactions with Cg(12) [C(26)–C(27)–C(28)–C(29)–C(30)–C(31)] and Cg(11) [C(15)–C(16)–C(17)–C(18)–C(19)–C(20)], respectively. , …”

“…In addition, a significant intramolecular C− H•••π interaction and two pairs of intramolecular π•••π interactions were also observed in complex 2. 36 The hydrogen atom, H(21C), attached to the carbon atom, C( 21 37,38 To elucidate the counter-anion effect on structures, M(OAc) 2 •4H 2 O was used to replace M(O 2 C 5 H 7 ) 2 to perform the same experiment. Notably, it will prevent metal(II) ions from entering the salamo pocket under the influence of counteranions, acetylacetone anions.…”

A flexible polydentate Salamo-Salen-Salamo hybrid ligand H 4 L was designed and synthesized, which has rich pockets (salamo and salen pockets) so that it may have fascinating coordination patterns with transition metal(II) ions. Four multinuclear transition metal(II) complexes, novel butterflyshaped homotetranuclear 4), have been synthesized and characterized by single-crystal X-ray diffraction. The effects of different anions [OAc − and (O 2 C 5 H 7 ) 2− ] on the complexation behavior of H 4 L with transition metal(II) ions were studied by UV−vis spectrophotometry. The fluorescent properties of the four complexes were studied with zebrafish, which are expected to be a potential light-emitting material. Ultimately, interaction region indicator (IRI) valuations, Hirshfeld surface analyses, density functional theory (DFT & TD-DFT), electrostatic potential analyses (ESP), and simulations were carried out to further demonstrate the weak interactions and electronic properties of the free ligand and its four complexes.

“…Such materials in the field of light-emitting diodes (LEDs), magnets, electrochemical displays, luminescent probes, and so on, are related to the magnetic and photoluminescence properties of rare earth elements. [10][11][12] As is well-known, the chemical and physical properties of rare earth materials are mainly related to the 4f electronic configuration of lanthanide ions. For example, if the 4f electrons of a lanthanide material can be transferred effectively, then photoluminescence is possible.…”

A novel up-conversion luminescence tetranuclear sodium complex [Na4(5-(carboxymethyl 2-oxo-propyl) amino isophthalic acid)(H2O)9] is synthesized by a solvothermal reaction, and its crystal structure is determined by single-crystal X-ray diffraction. The title complex crystallizes as a triclinic system with the P [Formula: see text] space group and exists as an isolated tetranuclear complex. Numerous intermolecular hydrogen bonds and van der waals forces form a three-dimensional supramolecular network. Solid-state diffuse reflectance data show that there is a wide optical band gap of 2.91 eV. The solid-state photoluminescence spectrum reveals that the complex shows an up-conversion emission in the blue region of the light spectrum. Time-dependent density functional theory calculations reveal that this emission can be attributed to ligand-to-ligand charge transfer.
