The binuclear title complex, di-μ-iodido-bis({2-[(benzylamino-κN)methyl]phenyl-κC1}palladium(II)), [Pd2I2(C14H14N)2], was prepared by reaction of [Pd{C6H4(CH2NHCH2Ph)-2}(μ-OAc)]2with NaI. It crystallizes with one discrete molecule in the asymmetric unit. The molecule presents an iodide-bridged dimeric structure with acisoidarrangement with respect to theC,N-cyclopalladated ligands. Both PdIIatoms have a slightly distorted square-planar coordination environment. Weak intermolecular contacts of the type C—H...Pd seem to have a significant influence on the arrangement of the molecules along thebaxis in the crystal.

Distorted Octahedral

The synthesis and crystal structure determination (at 293 K) of the title complex, Cs[Fe(C8H6BrN3OS)2], are reported. The compound is composed of two dianionicO,N,S-tridentate 5-bromosalicylaldehyde thiosemicarbazonate(2−) ligands coordinated to an FeIIIcation, displaying a distorted octahedral geometry. The ligands are orientated in two perpendicular planes, with the O- and S-donor atoms incispositions and the N-donor atoms intranspositions. The complex displays intermolecular N—H...O and N—H...Br hydrogen bonds, creatingR44(18) rings, which link the FeIIIunits in theaandbdirections. The FeIIIcation is in the low-spin state at 293 K.

The complete molecule of the hexametallic title complex, namely, tetrabromidotetra-μ-hydroxido-hexakis[μ-2-methyl-3-(pyrrolidin-1-yl)propan-2-olato]hexazinc(II) acetone disolvate, [Zn6Br4(C9H18NO)4(OH)4]·2C3H6O2, is generated by a crystallographic centre of symmetry. Two of the unique zinc atoms adopt distorted ZnO2NBr tetrahedral coordination geometries and the other adopts a ZnO3N tetrahedral arrangement. Both unique alkoxide ligands are N,O-chelating and both hydroxide ions are μ2 bridging. The crystal structure displays an O—H...O hydrogen bond between a μ2-OH group and an acetone solvent molecule. The Hirshfeld surface has been calculated and is described.

AbstractThe title complex has been prepared from Ga[GaBr4] and [2](1,4)naphthalino[2]paracyclophane in toluene as a solvent, and the crystal structure of this adduct determined by single crystal X-ray diffraction. The structure is composed of dimeric units Ga2[GaBr4]2 , which are crosslinked into sheets through Ga(I)-arene coordination. Both the benzene ring and the substituted ring of the naphthalene system are η6-bonded from the outer side of the cyclophane cage, each to an univalent metal. The benzene and the naphthalene form an interplane angle of 49.3°. The distance to the benzene ring (2.67 Å) is much shorter than the distance to the naphthalene (2.85 Å), suggesting a stronger complexation with the unperturbed π-system of the former. [2.2](l,4)Naphthalinophane forms no adduct with Ga[GaBr4], and with [2](l,5)naphthalino[2]paracyclophane secondary reactions are observed.

The title complex, [PdCl2(C8H14N2O)2]·2H2O, was obtained by N–O bond cleavage of the oxadiazoline rings of thetrans-[dichlorido-bis(2,5,5-trimethyl-5,6,7,7a-tetrahydropyrrolo[1,2-b][1,2,4]oxadiazole-N1)]palladium(II) complex. The palladium(II) atom exhibits an almost square-planar coordination provided by twotrans-arranged chloride anions and a nitrogen atom from each of the two neutral organic ligands. In the crystal, N—H...O, O—H...O and O—H...Cl hydrogen bonds link complex molecules into double layers parallel to thebcplane.

Reactions between Ru3(μ-H)(μ3-SBut)(CO)9 and dppm have given Ru3(μ-H)(μn- SBut)(μ-dppm)(CO)10-n(n = 2,3); hydrogenation of all three complexes resulted in S-C bond cleavage and formation of Ru3(μ-H)2(μ3-S)(CO)7(L2) [L2 = (CO)2, μ-dppm]. Facile substitution of 2CO in Ru3(μ-H)2(μ3-S)(CO)9 by dppm, dpam or ebdp (L2), catalysed by Na+[Ph2CO]- or [ppn][OAc], gave Ru3(μ-H)2(μ3-S)(μ-L2)(CO)7, in which the bis-tertiary phosphine (or arsine) bridges an edge of the Ru3 triangle, with the P (or As) atoms occupying equatorial positions. In the case of L2 = ebdp, this edge is also bridged by H, as shown by a single-crystal X-ray structure determination. Crystals of the title compound are mcnoclinic, space group P21/n, with unit cell parameters a 13.454(3), b 17.748(2), c 14.706(2) Ǻ, and β 94.50(1)°. The structure was refined by a full-matrix least-squares method; at convergence R and Rw were 0.036 and 0.038, respectively, for 4729 reflections with I ≥ 3.0σ(I).
