Wikipedia network analysis of cancer interactions and world influence

We apply the Google matrix algorithms for analysis of interactions and influence of 37 cancer types, 203 cancer drugs and 195 world countries using the network of 5 416 537 English Wikipedia articles with all their directed hyperlinks. The PageRank algorithm provides the importance order of cancers ...

Interactions of pharmaceutical companies with world countries, cancers and rare diseases from Wikipedia network analysis

Using the English Wikipedia network of more than 5 million articles we analyze interactions and interlinks between the 34 largest pharmaceutical companies, 195 world countries, 47 rare renal diseases and 37 types of cancer. The recently developed algorithm of reduced Google matrix (REGOMAX) allows ...

Crystal structure of di-[mu]-iodido-bis­[bis(aceto­nitrile-[kappa]N)copper(I)]

The title compound, [Cu2I2(CH3CN)4], exhibits a centrosymmetric Cu2I2 core [Cu...Cu distance = 2.7482 (11) Å], the CuI atoms of which are further coordinated by four mol­ecules of aceto­nitrile. The CuI atom has an overall distorted tetra­hedral coordination environment evidenced by L-Cu-L angles (L ...

Crystal structure of di-[mu]-iodido-bis­[(dimethyl sulfoxide-[kappa]O)(tri­phenyl­phosphane-[kappa]P)copper(I)]

The centrosymmetric dinuclear title compound, [Cu2I2(C2H6OS)2(C18H15P)2], represents the first example of a CuI complex ligated by an O-bound dimethyl sulfoxide ligand. In the crystal, the two tetrahedrally coordinated CuI atoms are bridged by two [mu]2-iodido ligands in an almost symmetrical ...

Crystal structure of tricarbon­yl([mu]-di­phenyl­phosphido-[kappa]2P:P)(methyl­diphenyl­silyl-[kappa]Si)bis(tri­phenyl­phosphane-[kappa]P)iron(II)platinum(0)(Fe-Pt)

The title compound, [FePt(C12H10P)(C13H13Si)(C18H15P)2(CO)3]·0.5CH2Cl2, represents an example of a phosphido-bridged heterobimetallic silyl complex; these are inter­esting precursors for the coordination and activation of small unsaturated organic mol­ecules. The [mu]2-PPh2 ligand spans the iron and ...

Diethyl 2,2'-(1,4-phenyl­enedi­oxy)­diacetate

In the title compound, C14H18O6, a crystallographic center at the centroid of the aromatic ring generates the complete mol­ecule which is planar within 0.085 (1) Å for the non-H atoms. In the crystal, weak C—H⋯O and C—H⋯π inter­actions link the molecules.

4,12-Bis(2,2-dibromo­vinyl)[2.2]paracyclo­phane

Dataset
Disciplines : crystallography
Collected date : from 2008 to 2009

In the title compound, C20H16Br4, both vinylic substituents were introduced by a Corey-Fuchs reaction using 4,12-diform­yl[2.2]paracyclo­phane as starting material. The title compound may be used as a valuable precursor for the synthesis of diethyn­yl[2.2]paracyclo­phane. The title mol­ecule is ...

4,4-Bis(4-methyl­phenyl­sulfan­yl)-1,1-diphenyl-2-aza­buta-1,3-diene

In the title compound, C29H25NS2, both the Cl atoms of the aza­diene precursor 4,4-dichloro-1,1-diphenyl-2-aza­buta-1,3-diene are replaced by two vicinal S-p-tolyl substituents attached to the terminal C atom of a [pi]-conjugated 2-aza­butadiene array. The aza­diene chain is planar to within 0.01 Å. ...

(2,2-Dichloro­vinyl)ferrocene

Dataset
Disciplines : crystallography
Collected date : from 2008 to 2009

The title compound, [Fe(C5H5)(C7H5Cl2)], represents a versatile building block for the preparation of [pi]-conjugated redox-active compounds or polymetallic organometallic systems due to the presence of the electrochemically active ferrocenyl unit. It is therefore a potential starting material for ...

Crystal structure of 4,4-di­bromo-1-(3,4-di­meth­­oxy­phen­yl)-2-aza­buta-1,3-diene-1-carbo­nitrile

The title compound, C12H10Br2N2O2, represents an example of a planar π-con­jugated 2-aza­butadiene mol­ecule, which is both an inter­esting starting material for further organic transformations and a potential ligand in organometallic coordination chemistry. Its metric mol­ecular parameters are ...
