The title compound, [CoH(C(18)H(15)P)(2)(C(2)H(6)OS)(2)], was synthesized by the reaction of chloridotris(triphenyl-phosphane)cobalt(I), [ClCo(PPh(3))(3)], in the presence of one equivalent potassium hydridotris(pyrazol-yl)borate in dimethyl sulfoxide. The structure displays a distorted trigonal-pyramidally coordinated cobalt(I) atom, with two phosphane ligands and one DMSO ligand in the equato...
A facile method to obtain polydisperse chemically-converted graphene sheets that are covalently functionalized with ionic liquid was reported -- the resulting graphene sheets, without any assistance from polymeric or surfactant stabilizers, can be stably dispersed in water, DMF, and DMSO.
The colloidal and biological properties of the two single-chain surfactants N-benzyl-N,N-dimethyl-N-(1-dodecyl)ammonium bromide (PH12) and N-cyclohexylmethyl-N,N-dimethyl-N-(1-dodecyl)ammonium bromide (CH12) and their two dimeric counterparts N,N'-(1,3-phenylenebis(methylene))bis(N,N-dimethyl-N-(1-dodecyl)ammonium dibromide (12PH12) and N,N'-(cyclohexane-1,3-diylbis(methylene))bis(N,N-dimethyl-...
The crystal structure of the title compound, [PtBr(C(15)H(11)N(3))][AuBr(2)]·(CH(3))(2)SO, exhibits infinite chains of {PtAuPt}(∞) metallophilic inter-actions along the b axis. Two cations and one anion stack in a trimer with a unique Pt⋯Au distance of 3.3361 (5) Å and Pt⋯Pt contacts of 3.4335 (6) Å. The remaining [AuBr(2)](-) anion forms no close contacts.
مقدمه: استفاده ی گسترده از داروهای گیاهی به دلیل اثرات حفاظتی آن ها بر ارگان های مختلف بدن در مطالعات بسیاری نشان داده شده است. سیلیمارین یک کمپلکس فلاونولیگنان مشتق از گیاه خار مریم (milk thistle) با نام علمی silybum marianum است. از این ترکیب، به علت داشتن اثرات ضد التهابی و حفاظتی در بیماری های کبدی (hepatoprotective) در کلینیک استفاده می شود. در سال های اخیر، اثرات تعدیل ایمنی (immunomodula...
In the heterodinuclear complex of the title compound, [PbZn(C(22)H(18)N(2)O(4))Cl(2)(C(2)H(6)OS)]·C(3)H(7)NO, the Zn(II) atom is coordinated in a distorted square-pyramidal geometry by two N atoms and two O atoms from the diphenolate ligand, and one Cl atom which occupies the apical position. The Pb(II) atom is coordinated in a distorted octa-hedral geometry by the four O atoms of the diphenola...
ETHALLY irradiated dogs usually recover promptly if given several billion fresh, autologous, marrow cells.1’2 Autologous marrow, stored at low temperature in glycerol or dimethyl-sulfoxide, induces a similar recovery.35 Recent studies of lethally irradiated mice have shown that infusions of fresh, isogenic leukocytes, if given in sufficient number, are followed by survival and return of marrow ...
