(tert-But-yl)(2-hy-droxy-eth-yl)ammonium chloride.

In the cation of the title mol-ecular salt, C6H16NO(+)·Cl(-), the N-C-C-O torsion angle is 176.5 (2)°. In the crystal, the cations and chloride ions are linked by N-H⋯O and O-H⋯O hydrogen bonds, generating a two-dimensional network parallel to (100).

cis-Bis(O-methyl-dithio-carbonato-κ(2) S,S')bis-(tri-phenyl-phosphane-κP)ruthenium(II).

In the title compound, [Ru(CH3OCS2)2(C18H15P)2], the Ru(II) atom is in a distorted octa-hedral coordination by two xanthate anions (CH3OCS2) and two tri-phenyl-phosphane (PPh3) ligands. Both bidentate xanthate ligands coordinate the Ru(II) atom with two slightly different Ru-S bond lengths but with virtually equal bite angles [71.57 (4) and 71.

Reactivity of Zn(II), Mg(II) and Al(III) chlorides with a phosphinimine ligand: new tetrameric inverse crown ether structures.

Reaction of [Me3SiNPPh2CH3] 1 with ZnCl2 yields the dimer [ClZn(mu-Cl)(Me3SiNPPh2CH3)]2 2 whereas treatment of 1 with AlCl3 in THF leads to the monomeric N adduct [Cl3Al(Me3SiNPPh2CH3)] 3. Compounds 2 and 3 were found to be thermally stable and were fully characterized by NMR spectroscopy, X-ray diffraction, and elemental analysis. On the other hand, treatment of phosphinimine 1 with (n)BuLi/ZnCl2 or (CH3)2CHMgCl yields the zinc and magnesium complexes [M4(Me3SiNPPh2CH2)4(mu4-O)(mu2-Cl)2] 5 (M = Zn) and 6 (M = Mg), respectively.

(Methyldiphenyl-phospho-ranylidene)-ammonium chloride.

The title compound, C(13)H(15)NP(+)·Cl(-), was obtained by hydrolysis of the N-trimethysilyl derivative of methydiphenyl-imino-phosphine. The dihedral angle between the phenyl rings in the cation is 61.5 (3)°.
