Five new copper(I)/silver(I) complexes containing 2-aminopyridine, [Cu(μ-Cl)(2-Apy)(PPh3)]2(1), [Ag(μ-Cl)(2-Apy)(PPh3)]2(2), [Ag(μ-Br)(2-Apy)PPh3)]2(3), [Ag(μ-ONO2)(2-Apy)(PPh3)]2(4), [Ag(μ-ONO2)(2-Apy)(AsPh3)]2(5) have been synthesised for the first time. Complexes 1–5 are obtained by the reactions of MX (MX = CuCl for 1; M = Ag for 2–5; X = Cl, Br for 2–3; X = NO3 for 4–5) with the monodentate ligands EPh3 (E = P for 1–4; E = As for 5) and 2-Apy in the molar ratio of 1:1:2 in the mixed solvent of CH2Cl2 and MeOH. Complexes 1–5 are characterised by IR and X-ray diffraction. In 1–5, chloride, bromide and nitrate ions bridge two metal atoms to form dinuclear complexes containing the parallelogram cores M2X2 (M = Cu, Ag). 相似文献

Cis-dioxo-catecholatotungsten(Ⅴ) complex (NH2CH2CH2NH3)4[WⅤO2(OC6H4O)2]2(NH3CH2CH2NH3)·H2O (1) was synthesized at room temperature by the reaction of tetrabutyl ammonium decatungstate with catechol in the mixed solvent of CH3OH, CH3CN and NH2CH2CH2NH2. The crystal structure of complex was determined by X-ray diffraction structural analysis. The results show that complex belongs to monoclinic system with space group P21/c,a=0.712 8(3) nm, b=3.082 3(11) nm, c=0.982 8(4) nm, β=102.639(6)°, V=2.106 8(14) nm3, Z=2, R1=0.062 8, wR2=0.183 7.

The vanadium(V) complexes K[VO2(SeO4)(H2O)] and K[VO2(SeO4)(H2O)2] · H2O were synthesized using original procedures; their physicochemical properties were studied, and the crystal structure was
determined on the basis of X-ray diffraction and neutron diffraction data. The structure of K[VO2(SeO4)(H2O)2] · H2O is composed of VO6 octahedra connected to form infinite chains by bridging SeO4 tetrahedra. Each VO6 tetrahedron has short terminal V-O bonds forming the bent dioxovanadium group VO2+ The unit cell parameters of K[VO2(SeO4)(H2O)2] · H2O are a = 6.4045(1) ?, b = 9.9721(2) ?, c = 6.6104(1) ?, β = 107.183(1)°, V = 403.34 ?3, Z = 2, monoclinic system, space group P21. The complex K[VO2(SeO4)(H2O)] forms a two-dimensional layered structure composed of highly distorted VO6 octahedra having two short terminal V-O bonds and SeO4 groups coordinated simultaneously by three vanadium atoms. This compound crystallizes in the monoclinic system (space group
P21/c): a = 7.3783(1) ?, b = 10.5550(2) ?, c = 10.3460(2) ?, β = 131.625(1)°, V = 602.894(5) ?3, Z= 4. The vibrational spectra of the studied compounds are fully consistent with their structural features. 相似文献

利用温度跃升傅立叶变换红外原位分析技术在0.1MPa氩气的条件下,对斯蒂酚酸碳酰肼铅和斯蒂酚酸碳酰肼镉的快速热分解过程进行了研究。研究结果表明,斯蒂酚酸碳酰肼铅的主要热分解气体为NH3, H2O和 HONO,而斯蒂酚酸碳酰肼镉的主要热分解气体为CO 和 NO,因此斯蒂酚酸碳酰肼镉不满足作为环境友好起爆药的使用要求。这两种化合物在快速热分解过程中均产生金属异氰酸盐、金属碳酸盐和金属氧化物。利用Real程序计算其燃烧温度可得斯蒂酚酸碳酰肼铅的燃烧温度要高于斯蒂酚酸碳酰肼镉,对其燃烧产物进行计算,发现HNCO不在燃烧产物之列,NO的含量也比实验得出的浓度要小。 相似文献

A convenient synthesis and the characterization of six new electronically and coordinatively unsaturated complexes of the formula [Ru2(CO)4(μ-H)(μ-PtBu2)(μ-L2)] (2b-g) (RuRu) is described exhibiting a close relation to the known [Ru2(CO)4(μ-H)(μ-PtBu2)(μ-dppm)] (2a). The complexes 2b-g were obtained in a kind of one-pot synthesis starting from [Ru3(CO)12] and PtBu2H in the first step followed by the reaction with the bidentate bridging ligand in the second step. The method was developed for the following bridging ligands (μ-L2): dmpm (2b, dmpm = Me2PCH2PMe2), dcypm (2c, dcypm = Cy2PCH2PCy2), dppen (2d, dppen = Ph2PC(=CH2)PPh2), dpppha (2e, dpppha = Ph2PN(Ph)PPh2), dpppra (2f, dpppra = Ph2PN(Pr)PPh2), and dppbza (2g, dppbza = Ph2PN(CH2Ph)PPh2). The molecular structures of all new complexes 2b−g were determined by X-ray diffraction. 相似文献

The compound [Os3(CO)10(μ-Cl)(μ-AuPPh3)] (2) was prepared from the reaction between [Os3(CO)10(NCMe)2] (1) and [AuClPPh3] under mild conditions. The reaction of 2 with 4-mercaptopyridine (4-pyS) ligand yielded compounds [Os3(CO)10(μ-H)(μ-SC5H4N)] (4), formed by isolobal replacement of the fragment [AuPPh3]+ by H+ and [Os3(CO)10(μ-AuPPh3)(μ-SC5H4N)] (5). [Os3(CO)10(μ-H)(μ-SC5H4N)] (4) was also obtained by substitution of two acetonitrile ligands in the activated cluster 1 by 4-pyS, at room temperature in dichloromethane. Compounds 2-5 were characterized spectroscopically and the molecular structures of 4 and 5 in the solid state were obtained by single crystal X-ray diffraction studies. 相似文献

The molecular structure was characterized by using X-ray diffraction analysis, element analysis and FTIR analysis. The crystal belongs to triclinic with space group P1.

Abstract
Products from the thermolysis of PhNCO and [MoO2(S2CNR2)2] (R = Me, Et) are highly dependent upon the reaction conditions. When carried out in air, the major products are cations, [Mo(NPh)(S2CNR2)3]+, as shown by a crystal structure of [Mo(NPh)(S2CNEt2)3]2[Mo6O19]. Under rigorously anaerobic conditions, reaction of two equivalents of PhNCO with [MoO2(S2CNR2)2] affords [Mo(NPh)2(S2CNR2)2] as the major product. However, chloroform solutions of the bis(imido) complexes hydrolyze in air to afford [Mo(NPh)(S2CNR2)2(μ-MoO4)]2, in which molybdate groups bridge between molybdenum(VI) imido-bis(dithiocarbamate) centers. These results are placed in context of our earlier studies of these reactions that lead to the formation of oxo-disulfide [MoS2(NPh)(S2CNR2)2] and dimeric molybdenum(V) [MoO(μ-NPh)(S2CNR2)]2 complexes, thus allowing a full picture of these transformations to be established. 相似文献18.

The γ-hydroxypropyl-functionalised diiron dithiolate complex [Fe2(CO)6(μ-SCH2CH2CH2OH)2] is prepared upon thermolysis of Fe3(CO)12 and HO(CH2)3SH and further reaction with dppm (dppm = Ph2PCH2PPh2) affords [Fe2(CO)4(μ-dppm)(μ-SCH2CH2CH2OH)2]. From the reaction of Fe3(CO)12 with dppm(S2) a minor product is the tetrairon cluster, [{Fe2(CO)6(μ-SCH2CH2CH2OH)}2(μ4-S)], the mode of formation of which is unclear. It has been crystallographically characterised and adopts a μ4-S bridged double butterfly structure which is compared with other crystallographically characterised complexes of this type.
