Syntheses,Crystal Structures and Thermal Properties of Two Dicadmiun(II) Complexes Cd_2L_2X_2(HL=N-(3-Methoxylsalicylidene)-3-dimethylaminopropylamine,X = Cl(1),NCS(2))

Two Cd(II) complexes, Cd2L2Cl2(1) and Cd2L2(NCS)2(2)(HL = N-(3-methoxyl-salicylidene)-3-dimethylaminopropylamine) were synthesized and determined by EA, IR, TG and single-crystal X-ray diffraction.The crystallographic data are as follows:monoclinic, space group P21/n, a = 9.2710(9), b = 18.0069(18), c = 18.5562(19) , β = 99.741(4)o, V = 3053.1(5), Z = 4, μ = 1.605, F(000) = 1536, R = 0.0264 and wR = 0.0699 for 1;orthorhombic, space group Pca21, a = 16.196(3), b = 11.506(2), c = 36.126(7), V = 6732(2), Z = 8, μ = 1.428, F(000) = 3264, R = 0.0376 and wR = 0.0877 for 2.There are two geometrically different octahedral Cd(II) atoms, with N4O2 and O4Cl2 donor sets for 1 while N4O2 and N2O4 for 2.In the dinuclear Cd(II) centers, the Cd(II) atoms are held together by two deprotonted phenolate oxygen atoms from tetradentate L-ligands.The thermal gravity data show two step decompositions with the residues of CdO for two complexes.     

Synthesis and Crystal Structure of (CH2)3(3, 5-Me2Pz)2·[PhBr2Sn(CH2)SnBr2Ph]·2HBr·2H2O (Pz = pyrazole)

The reaction of bis(dibromophenylstannyl)methane with 1, 3-bis(3, 5-dimethyl- pyrazol-1-yl)propane in a 1:1 or 1:2 ratio yields only 1:1 adduct which partly hydrolyzes to the title complex (C26H38Br6N4O2Sn2, Mr = 1155.42) during crystal growing. The title complex is of triclinic, space group P ī with a = 10.886(1), b = 12.508(1), c = 13.879(1) ?, α = 85.762(2), β = 85.159(2), γ = 84.020(2)°, V = 1868.8(4) ?3, Z = 2, Dc = 2.046 g/cm3, λ(MoKα) = 0.71073 ?, μ = 7.778 mm-1, F(000) = 1088, R = 0.0488 and wR = 0.1157 for 7560 observed reflections with I ≥ 2σ(I). The crystal structure analysis indicates that there is no direct interaction between the ligand and bis(dibromophenylstannyl)methane, and two tin atoms are bridged by two bromide atoms from the partial hydrolysis of this adduct.     

Synthesis, Crystal Structure and Luminescent Property of a Novel 1-D Cadmium(II) Complex: [Cd_2(C_8H_3NO_6)_2(H_2O)_4]_n·2nH_2O

A novel one-dimensional chain-like coordination polymer constructed from 3-nitro- benzene-1,2-dicarboxylic acid, [Cd2(C8H3NO6)2(H2O)4]n·2nH2O, has been synthesized and its structure was determined by X-ray crystallography method. The crystal belongs to monoclinic, space group P21/c with a = 6.1252(8), b = 20.706(3), c = 8.8067(11) , β = 95.608(2)°, V = 1111.6(2) 3, Mr = 751.12, Dc = 2.244 g/cm3, F(000) = 736, μ = 2.011 mm-1, Z = 2, the final R = 0.0262 and wR = 0.0692 for 2338 observed reflections with I > 2σ(I). The structure of the title compound presents a 1-D chain-like structure constructed by dimer units, [Cd2(C8H3NO6)2(H2O)4]n, through two carboxylate oxygen atoms. The fluorescence of the title compound has been also discussed in this paper.     

Synthesis and crystal structures of two new Cd(II) complexes with 3-(2-pyridy)pyrazole-based ligand: influence of anions

Two new Cd(II) complexes with a 3-(2-pyridyl)pyrazole-based ligand, [Cd(L)₂(SCN)₂] (1) and {[Cd(L)₂N₃](ClO₄)}_n (2) (L=3-(2-pyridyl)pyrazol-1-ylmethylbenzene) were synthesized and structurally characterized by elemental analyses, IR and single crystal X-ray diffraction analysis. Complex 1 crystallizes in the monoclinic system, space group C2/c, with a=14.833(3), b=13.790(3), c=15.970(3) Å, β=110.89(3)° and Z=4, while 2 crystallizes in the monoclinic system, space group P2₁/c, with a=13.622(4), b=23.286(7), c=10.547(3) Å, β=111.084(6)° and Z=4. In the two complexes, the Cd(II) centers are coordinated by six nitrogen atoms, in which four from two distinct L ligands and two from thiocyanato (1) or azido (2) anions. Complex 1 has a mononuclear structure, whereas 2 has a 1D chain structure bridged by azido anions. In 2, the azido adopts a μ-1,3-trans coordination mode, which is not common in the azide Cd(II) complexes. In addition, in the structure of 2, the 1D chains were further assembled into a quasi-3D supramolecular network by the C–HO hydrogen-bonding interactions. The structural difference of the two complexes is attributable to the different anions, which have different coordination natures.     

Synthesis and Crystal Structure of (CH_2)_3(3,5-Me_2Pz)_2. [PhBr_2Sn(CH_2)SnBr_2Ph].2HBr.H_2O (Pz=pyrazole)

1 INTRODUCTION The coordination chemistry of tin or organotin toward poly(pyrazol-1-yl)borate ligands has been extensively investigated in recent years owing to the antitumor activity of some related organotin derivatives containing N-donor ligands. A number of organotin(Ⅳ) complexes containing poly(pyrazol- 1-yl)borate ligands have been synthesized and characterized[1~3], some of which have also shown interesting structural characteristics and reactivities[4~6]. Recently, poly(pyrazol…     

Reaction of Mo(CO)_6 with Alkoxide: Synthesis and Structure of the Mo(0)-OR Complex [Et_4N]_3[Mo_2(CO)_6(μ-OC_6H_4OCH_2C_6H_5)_3]

The reaction of molybdenum hexacarbonyl with C6H5CH2OC6H4ONa and Et4NBr in CH3CN at 60 ℃ afforded the di-nuclear Mo(0) compound [Et4N]3[Mo2(CO)6(μ-OC6H4OCH2- C6H5)3] 1. 1 crystallizes in monoclinic, space group P21/c with a = 15.359(2), b = 18.378(3), c = 24.952(2), β = 102.268(4)°, V = 6882.3(16) 3, Mr = 1348.34, Z = 4, Dc = 1.301 g/cm3, F(000) = 2832 and μ = 0.424 mm-1. The final R = 0.0606 and wR = 0.1552 for 9396 observed reflections (I > 2σ(I)). 1 contains a [Mo2O3]3- core in triangular bi-pyramidal configuration and each Mo atom adopts a distorted octahedral geometry with three carbon atoms from carbonyls and three μ-O atoms from C6H5CH2OC6H4O- bridging ligands. The Mo…Mo distance is 3.30(8) , indicating no metal- metal bonding. A formation pathway via forming a di-molybdenum(0) di-bridging OR compound [Mo2(μ-OR)2(CO)8]2- has been figured out and the reaction of Mo(CO)6 with alkoxide has also been discussed.

The fluorescence of the tifle compound has been also discussed in this paper.

Synthese und Kristallstrukturen der Samarium-Komplexe [SmI2(DME)3] und [Sm2I(NPPh3)5(DME)]

Synthesis and Crystal Structures of the Samarium Complexes [SmI₂(DME)₃] and [Sm₂I(NPPh₃)₅(DME)] When treated with ultrasound, the reaction of samarium metal with N-iodine-triphenylphosphaneimine in 1,2-dimethoxyethane (DME) leads to the two samarium complexes [SmI₂(DME)₃] ( 1 ) and [Sm₂I(NPPh₃)₅(DME)] ( 2 ), which are separated from each other by fractional crystallization. 1 could be isolated in two different crystallographic forms, namely as brownish black crystals ( 1 a ) and as violet-black crystals ( 1 b ), both of them are characterized by crystal structure analyses. 1 a : Space group P2₁/c, Z = 4, lattice dimensions at –80 °C: a = 1459.4(1), b = 1314.4(1), c = 2293.6(2) pm, β = 99.245(8)°, R = 0.0344. The structure of 1 a holds two crystallographically independent molecules [SmI₂(DME)₃], in which the samarium atoms have coordination number eight. The two individuals differ from each other particularly in their I–Sm–I bond angles, which are 157.94 and 178.45°. 1 b : Space group P2₁, Z = 2, lattice dimensions at –80 °C: a = 849.4(3), b = 1060.1(3), c = 1235.1(6) pm, b = 93.86(5)°, R = 0.0251. 1 b has a molecular structure similar to that of 1a with a bond angle I–Sm–I of 158.40°. The phosphoraneiminato complex [Sm₂I(NPPh₃)₅(DME)] ( 2 ) forms colourless, moisture sensitive crystals which contain two molecules DME per formula unit. 2 · 2 DME: Space group P1, Z = 2, lattice dimensions at –80 °C: a = 1405.0(4), b = 1656.5(3), c = 2208.3(7) pm, α = 89.60(3)°, β = 72.96(4)°, γ = 78.70(3)°, R = 0.0408. In 2 the two samarium atoms are linked via the μ-N atoms of two phosphoraneiminato ligands to form a planar Sm₂N₂ four-membered ring. One of the Sm atoms is terminally coordinated by the N atoms of two (NPPh₃)^– groups, thus achieving a distorted tetrahedral surrounding. The second Sm atom is coordinated by the N atom of one (NPPh₃)^– group, by the terminally bonded iodine atom, and by the O atoms of the DME chelate, thus achieving a distorted octahedral surrounding.
