Structure and dynamics of heterometallic clusters derived from addition of metal carbonyl fragments to the unsaturated hydride [W2Cp2(μ-H)(μ-PPh2)(NO)2]

The title complex, [Ir(C5H8NO2)H(C3H9P)3]PF6, has two independent anion–cation pairs in the asymmetric unit. The geometry about each IrIIIatom is pseudo-octahedral with a meridional arrangement of the P(CH3)3ligands,N,O-bidentate coordination of prolinate and a hydride ligandtransto the prolinate N atom. The independent IrIIImoieties are joined by N—H...O hydrogen bonds and the N—H...O bonding motif continues throughout the structure, creating an extended chain parallel to thec-axis direction. The methyl groups of one P(CH3)3ligand are rotationally disordered over two sets of sites in a 0.62 (2):0.38 (2) ratio.

The title complex, [Os3(C2H4N)H(CO)10] or [Os3(CO)10(μ-H)(μ-HN=C—CH3-1κN:2κC)], was synthesized in 41.6% yield by reactions between Os3(CO)11(CH3CN) and 2,4,6-trimethylhexahydro-1,3,5-triazine. The central osmium triangle has two OsI atoms bridged by a hydride ligand and a μ-HN= C—CH3-1κN:2κC triazine fragment. Three CO ligands complete the coordination sphere around each OsI atom, while the remaining Os0 atom has four CO ligands. Each Os atom exhibits a pseudo-octahedral coordination environment, discounting the bridging Os—Os bond.

Chromatin Structure And Dynamics

In the 30 years since the discovery of the nucleosome, our picture of it has come into sharp focus. The recent high-resolution structures have provided a wealth of insight into the function of the nucleosome, but they are inherently static. Our current knowledge of how nucleosomes can be reconfigured dynamically is at a much earlier stage. Here, recent advances in the understanding of chromatin structure and dynamics are highlighted. The ways in which different modes of nucleosome reconfiguration are likely to influence each other are discussed, and some of the factors likely to regulate the dynamic properties of nucleosomes are considered.
