“…The donor atoms of two deprotonated ligand L 3were coordinated to nickel(II) ions to form a square-planar/octahedral/ square-planar linear trinuclear complex in each mole- cule. This is similar to the coordination geometry of few trinuclear nickel(II) complexes 16,19,20 in which three nickel(II) atoms also exhibit alternating square-planar and octahedral coordination environments. The two molecules exhibit crystallographic centrosymmetry.…”

2), were prepared by the reaction of Ni(OAc) 2 •4H 2 O with N-hexanoylsalicylhydrazide. The crystal structures of complexes were determined by X-ray diffraction analysis. Complex 1 takes triclinic symmetry with space group P-1 and cell dimensions of a＝0.92377(2) nm, b＝1.08786 (6) nm, c＝1.29391(3) nm, α＝76.395(4)°, β＝78.418(3)°, γ＝67.378(4)°, V＝1.15772(7) nm 3 , Z＝1, µ＝12.63 cm -1 . Complex 2 belongs to triclinic system and P2(1) space group and the crystallographic data: a＝1.4889(2) nm, b＝1.0389(1) nm, c＝1.4994(2) nm, β＝ 96.174(4)°, V＝2.3058(5) nm 3 , Z＝2, µ＝12.70 cm -1 . The structures of the two molecules are similar. The threenickel atoms in each molecule of the two title complexes arrange in a strictly linear structure. The central nickel atom of the molecule adopts octahedral configuration, while the two nickel atoms on the two sides adopt square-planar configuration in each molecule. But the central nickel atoms of the two complexes have different axial ligands, which cause a slight difference in the bond distances of the octahedron. The antibacterial activity of compound 1 against seven common bacteria was investigated.

“…As a multifunctional thiolato ligand with oxygen and sulfur donors, 2-mercaptophenol (H 2 mp) can chelate to and/or bridge various metal ions to exhibit versatile coordination modes: 8 HO t S t , HOS b , O t S t , O b S t , and O b S b -B (where b stands for bridge, t for terminal, and B for binuclear). When phosphine is involved in the reactions, nickel and cobalt clusters 3a,b have been obtained where four more coordination modes, i.e., HOS t , HO t S b , O t S b , and O b S b -T (where T stands for trinuclear), have been observed. It has been shown that the mixed ligand metal complexes of 2-mercaptophenol and are highly complex and diverse.…”

The reaction of CoCl 2 , RuCl 3 , Na 2 (mp), and PBu n 3 (H 2 mp ) 2-mercaptophenol, PBu n 3 ) tri-n-butylphosphine) in ethanol in the molar ratio of 0.75:0.25:1:1 gave the complex Co 6 Ru 2 (mp) 10 (PBu n 3 ) 6 . The heterooctanuclear complex consists of six cobalt and two ruthenium ions chelated to as well as bridged by the 2-mercaptophenol ligands in a near-dimeric fashion with two µ 2 -OR groups bridging the two Co 3 Ru(mp) 5 (PBu n 3 ) 3 fragments without a crystallographic center of symmetry. Each fragment is formed by binding two of the Co(mp) 2 (PBu n 3 ) structural units and one Co(mp) species to a central Ru(III) ion through the S donors of the five mp ligands, while the sixth coordination site of the octahedral Ru environment is completed by a phosphine ligand in the axial position. The Co 6 Ru 2 moiety exhibits a zigzag assembly constructed by the µ 2 -O and µ 2 -S bridges of the bidentate 2-mercaptophenol ligands in a highly asymmetric fashion. The Co atoms are square pyramidally coordinated with apices that are occupied by the phosphine ligands or an oxygen atom from a mp 2ligand. Variable-temperature magnetic susceptibilities that were measured in the temperature range 300-1.6 K reveal that the spin cluster exhibits weak antiferromagnetic exchange interactions. A quantitative interpretation of the magnetic data was carried out by the irreducible tensor operator approach. Crystal data of the complex are as follows: triclinic space group P1 h, a ) 14.931(3) Å, b ) 23.195(5) Å, c ) 24.259(5) Å, R ) 74.91(3)°, β ) 74.83(3)°, γ ) 78.80(3)°, and Z ) 2.

Neutral heterotetranuclear complex Co·~Fe(mpMHmp)(PBun3h 2 (PBu n) -,; tri-n-butylphospbme) of 2mercaptophenol (Hjmp) was synthesized in a molar ratio of CoCI2:FeCI3:Hzmp:NaOMe:PBun3 ; 0.75:0.25: I :2: I under anaerobic conditions. It represents partially Few·substituted form of the asymmetric mixed-valence tetracobalt complex C0 4(mpMHrnp)(PBu'\)3 (1). 2 crystallizes in the triclinic space group pI, with a:; 12.373(2) A, b =15.677(3) A, c:; 20.571 (4) A, a:; 93.59(3)",~== 93.45(3)", Y== 112.300)" , V = 3669 A\ and Z:; 2. The molecule exhibits a cyclic skeleton of Co 3FeS4 0 3 with two doubly Ilz-S bridges, one doubly 1l2-0 bridge, and one singly 1l2-0 bridge. The four mp" ligands display two different modes, QhSb"T and 0tSb, while the monoanion Hmp is only terminally chclated to Fe 3 + ion in HOISt fashion (h stands for bridge, t for terminal, and T for trinuclear). The three Co centers are located in approximately square-based pyramidal environments, and the Fe atom in distorted trigonal bipyramidal geometry. Three types of main fragment ions were observed in the FAD mass spectrum of 2. The dissociation of the fragments follows the order: PBu") first, then Hmp and mp ligands. Moreover, the dissociation of Fe(Hmp) is first, followed by Co(mp) and Cotrnpj-, according with the fact that Fe(Hmp) is only loosely bonded. Variable-temperature magnetic susceptibility measurements showed that 2 exhibits weak magnetic exchange iIIteractions. 367
