Aquachlorido(2,2′:6′,2′′-terpyridyl)copper(II) chloride monohydrate

Autor: Laurette Schmitt, Gaël Labat, Helen Stoeckli-Evans

Publikováno v: Acta Crystallographica Section E, Vol 66, Iss 9, Pp m1169-m1169 (2010)

The title complex, [CuCl(C15H11N3)(H2O)]Cl·H2O, is composed of a monocation that possesses mirror symmetry. The CuII atom has a distorted square-pyramidal geometry, being coordinated by the three N atoms of the terpyridine ligand and a Cl atom in th

Two dipolar biphenyls show significant 180° orientational disorder resulting in bipolar as-grown crystals. An added symmetrical biphenyl interferes with polarity formation and inverts the initial bipolar state.

Publikováno v: Liu, Shi-Xia; Ambrus, Christina; Dolder, Stefan; Neels, Antonia; Labat, Gaël; Decurtins, Silvio (2006). Structure and magnetic properties of the radical cation salt of a TTF-based Ni(II) complex. Journal of low temperature physics, 142(3-4), pp. 457-460. Dordrecht: Springer 10.1007/s10909-006-9137-4

Chemical oxidation of a TTF-based NiII complex with I2 produces the corresponding radical cation salt 1, [Ni2Cl2(L)2](I3)2(I5)2(I2)(H2O)2(C4H8O)3, (L=4,5-bis(2-pyridylmethylsulfanyl)-4',5'-ethylenedithiotetrathiafulvalene). The results of magnetic su

Pyroelectric and piezoelectric scanning microscopy applied to reveal the bipolar state of 4-iodo-4'-nitrobiphenyl (INBP)

Autor: Alessio Morelli, Gaël Labat, Michel Bonin, Matthias Burgener, J. Hulliger

Publikováno v: CrystEngComm

Two recent scanning probe techniques were applied to investigate the bipolar twin state of 4-iodo-4′-nitrobiphenyl (INBP) crystals. Solution grown crystals of INBP show typically a morphology which does not express that of a mono-domain polar struc
