We present the ?3-coordination of 2-phosphaethynthiolate anion in complex (PN)2La(SCP) (2) [PN=N-(2-(diisopropylphosphanyl)-4-methylphenyl)-2,4,6-trimethylanilide)]. Structural comparison with dinuclear thiocyanate-bridged (PN)2La(?-1,3-SCN)2La(PN)2 (3) and azide-bridged (PN)2La(?-1,3-N3)2La(PN)2 (4) complexes indicates that [SCP]? coordination mode is mainly governed by electronic, rather than...

A new cobalt(III) complex with a pentadentate Schiff base was synthesized using reaction of 2,2′-{(2-hydroxypropane-1,3-diyl)bis(nitriloeth-1-yl-1-ylidene)}diphenol (H3L) and cobalt(II) acetate in methanolic solution. This synthesis resulted the isolation dinuclear compound [CoIII2L2] (1), which characterized elemental analyses XRF, FTIR, TG/DSC techniques. The molecular structure confirmed sin...

Two dinuclear [Ni2L2(o-(NO2)C6H4COO)2(H2O)] (1), [Ni2L2(p-(NO2)C6H4COO)2(H2O)]·0.5CH3OH (2) complexes and one trinuclear [Ni3L2(p-(NO2)C6H4COO)4]·C2H5OH (3) Ni(II) complex have been synthesized using a tridentate Schiff base ligand, 1-[(3-dimethylamino-propylimino)-methyl]-naphthalen-2-ol (HL) along with ortho- and para-nitro benzoate as co-ligands. All these three (1-3) complexes have been cha...

In the title compound, [Nd(2)(C(6)H(3)BrNO(2))(6)(H(2)O)(4)]·2H(2)O, the Nd(III) ion is coordinated by nine O atoms from one chelating 5-bromo-nicotinate ligand, four bridging 5-bromo-nicotinate ligands and two water mol-ecules, exhibiting a distorted three-capped triangular-prismatic geometry. Two Nd(III) ions are bridged by four carboxyl-ate groups in bi- and tridentate modes, forming a centr...

A series of four related phenol derivatives, with 2,2'-dipicolylamine substituents at the ortho positions, were prepared and their Zn2+ coordination complexes studied by spectroscopic methods. X-ray crystal diffraction analysis of a dinuclear zinc complex with two bridging acetate anions showed a ternary structure with highly charged interior and lipophilic exterior, which helps explain why thi...

The title coordination polymer, [Pb(2)(N(3))(3)(NO(2))(C(12)H(8)N(2))(2)](n), has as the repeat unit a centrosymmetric dinuclear mol-ecule having azide and nitrite groups that bridge adjacent heterocycle-coordinated metal centers. One of the azide group uses its terminal ends to bridge whereas the nitrite group chelates to one metal atom and uses one of its O atoms to bridge. The azide and nitr...

Oximato bridged dinuclear copper(II) complex [Cu(L)(CH3OH)]2(ClO4)2 with an oxime-Schiff base ligand, viz. 3-[2-[(dimethylamino)ethyl]imino]-2-butanoneoxime (HL), has been synthesized and structurally characterized. The dinuclear copper(II) complex crystallizes in monoclinic space group P21/n with the unit cell parameters, a = 13.3564(9) Å, b = 12.0821(8) Å, c = 17.5045(11) Å, β = 90.097, V = 2...

Copper(II) complexes with 2,3,4-trimethoxybenzoic acid (H234-tmbz) and 2,4,6-trimethoxybenzoic (H246-tmbz), [Cu2(234-tmbz)4(H2O)2] (6) [Cu(246-tmbz)2(µ-H2O)2(H2O)2]n (7), were synthesized characterized by elemental analysis, infrared UV-vis spectra temperature dependence of magnetic susceptibilities (1.9–300 K). The X-ray crystal structures revealed that the former 6 is a dinuclear cluster havi...

The new acyclic and potentially heptadentate dinucleating ligand, 2,6-bis(N,N-bis-(2-pyridylmethyl)-sulfonamido)-4-methylphenolato (bpsmp(-)) contains two tertiary sulfonamide groups. The sulfonamide donors permit a greater degree of control over the accessibility of mono versus dinuclear complexes compared to their closely related amine-containing counterparts, on account of their relatively w...
