چکیده
The title compound, C(16)H(18)O(2)P(2), possesses two stereogenic P atoms and shows a distorted s-cis conformation of each O=P-C=C moiety. This has been suggested on the basis of the stereochemical result of 1,3-dipolar cyclo-additions with nitro-nes and is now confirmed by the present crystal structure analysis. There are two crystallographically independent molecules in the asymmetric unit.

The asymmetric unit of the title ion-pair complex, (C(9)H(12)NO(2))(2)[Ni(C(4)N(2)S(2))(2)], contains two 1-(eth-oxy-carbonyl-meth-yl)pyridinium cations and one bis-(1,2-dicyano-ethene-1,2-dithiol-ato)nickelate(II) dianion, which exhibits a slightly distorted square-planar coordination geometry. In the crystal, the cations are linked by strong C-H⋯O hydrogen bonds into C(6) chains along [100]. ...

In the title compound, [Ni(2)(C(2)H(4))(2)(C(25)H(22)P(2))(2)]·2C(7)H(8), each Ni atom is coordinated in a trigonal-planar geometry by two P atoms of the bridging 1,2-bis-(diphenyl-phosphino)methane (dppm) ligands and by the centroid of the double bond of an ethene ligand. An eight-membered ring comprising the two Ni atoms, four P atoms and the CH(2) groups of the two dppm ligands is thus forme...

In the title compound, [Ni(C(20)H(13)O(5)P)(C(12)H(10)N(2))(H(2)O)](n), the Ni(II) cation is coordinated by three O atoms from two 5-(diphenyl-phosphino-yl)isophthalate anions, two N atoms from two 1,2-bis-(pyridin-4-yl)ethene ligands and one water mol-ecule in a distorted octa-hedral geometry. Both 1,2-bis-(pyridin-4-yl)ethene and 5-(diphenyl-phosphino-yl)iso-phthal-ate bridge the Ni(II) catio...
