“…Thus, two pairs of intramolecular hydrogen bonds C9-H9B···O7, C9 # -H9B # ···O7 # , O9-H9···O5 and O9 # -H9 # ···O5 # [53][54][55][56][57][58][59] are formed. Under the intermolecular force of C7-H7···O6 and C7 # -H7 # ···O6 # , a 1D supramolecular chain that extends infinitely in the b axis direction is formed by the crystal of [{Zn(L)(µ-OAc)Zn(CH 3 CH 2 OH)} 2 ], as depicted in Figure 4 [60][61][62][63][64][65][66][67]. The complex [{Zn(L)(µ-OAc)Zn(CH3CH2OH)}2] belongs to the triclinic system, with space group P-1, and consists of four zinc(II) atoms and two completely deprotonated (L) 3− linkers, with two ethanol molecules and two bonded acetate ions.…”

Abstract:A new tetranuclear zinc(II) complex with an asymmetrical Salamo-type chelating ligand, H 3 L (5-methoxy-6 -hydroxy-2,2 -[ethylenedioxybis(nitrilomethylidyne)]diphenol), was synthesized and characterized using FT-IR, elemental analyses, X-ray single crystal diffraction method, UV-Vis, and fluorescence spectra. The zinc(II) complex possesses the cell parameters a = 8.1960(7) Å, b = 9.8127(8) Å, c = 16.5428(15) Å, Z = 1, V = 1172.5(2) Å 3 , R 1 = 0.0722, and wR 2 = 0.1558, and crystallizes in the triclinic system, with space group P-1. X-ray crystal structure analysis reveals that Zn1 and Zn2 atoms are all pentacoordinated and adopt slightly twisted tetragonal pyramidal and trigonal bipyramidal geometries. The zinc(II) complex forms a 1D supramolecular chain via intermolecular hydrogen bonds along the b axis. Besides, the fluorescence properties have been discussed.

“…Recently, a new N 2 O 2 -type analogue, the Salamo ligand was developed [27][28][29][30][31][32]. Interestingly, other works have contributed to researching mono-, multi-, homo-or heteromultinuclear metal coordination compounds having Salamo-type ligands or their derivatives [33][34][35].…”

Abstract:One trinuclear Co(II) coordination compound [{CoL 1 (OAc)(CH 3 COCH 3 )} 2 Co] (1) and one unprecedented mononuclear Ni(II) coordination compound [Ni(L 2 ) 2 ] (2), constructed from a Salamo-type ligand H 2 L 1 were synthesized and characterized by elemental analyses, IR, UV-vis spectra, and single crystal X-ray diffraction analyses. The results show that the Co(II) atoms have no significant distortion in CoO 6 or CoO 4 N 2 octahedrons in coordination compound 1. Interestingly, in coordination compound 2, the desired tri-or mono-nuclear Salamo-type Ni(II) coordination compound was not obtained, but an unprecedented Ni(II) coordination compound [Ni(L 2 ) 2 ] was synthesized, the Ni1 atom having no significant distortion in the NiO 2 N 2 planar quadrilateral geometry. Furthermore, the antimicrobial activities of coordination compound 1 and previously reported coordination compound [{CoL 1 (OAc)(MeOH)} 2 Co]·2MeOH (3) are discussed.

“…Salen-type ligands and their coordination compounds have been extensively investigated [1][2][3][4][5][6][7][8][9][10] for their catalytic activities [11][12][13][14][15], biological activities [16][17][18][19][20][21][22], supramolecular architectures [23][24][25][26][27][28][29][30][31][32], and fluorescence properties [33][34][35][36][37][38]. To improve the properties of Salen-type ligands, in recent years, Nabeshima and our group's researches mostly concentrated on the syntheses of Salamo-type ligands, which are a class of novel Salen-type analogues [39][40][41][42][43][44][45][46][47][48]…”

Abstract:The newly designed butterfly-shaped hetero-tetranuclear Cu II -Na I coordination compound, [Cu 3 (HL) 2 Na]·Pic (Pic − is abbreviation of picrate) (1) which is derived from a naphthalenediol-based bis(Salamo)-type chelating ligand H 4 L have been synthesized and characterized by elemental analyses, UV-vis spectra, IR spectra analysis, and Hirshfeld surface analysis. X-ray crystallographic analyses revealed that the coordination compound 1 is a novel hetero-tetranuclear Cu II -Na I bis(Salamo)-type coordination compound and it differs from heterotrinuclear Cu II -Na I bis(Salamo)-type coordination compound reported earlier. The Cu1 and Cu3 atoms are tetra-coordinated with geometries of distorted square pyramid, while Cu2 atom are hexa-coordinated with the geometry of a distorted octahedron. The Na I atom is octa-coordinated with the geometry of a distorted hexagonal bipyramid. Furthermore, the supramolecular structure and Hirshfeld surface analyses have been discussed in detail.
