A hexanuclear gold carbonyl cluster.
The hexanuclear gold carbonyl cluster [PPh4]2[Au6(CF3)6Br2(CO)2] (4) has been obtained by spontaneous self-assembly of the following independent units: CF3AuCO (1) and [PPh4][Br(AuCF3)2] (3). The cyclo-Au6 aggregate 4, in which the components are held together by unassisted, fairly strong aurophilic interactions (Au···Au ∼310 pm), exhibits a cyclohexane-like arrangement with chair conformation....
متن کاملEffect of two gold compounds on lysosomes.
The effect of two gold(I) compounds on stability of lysosomes in vitro was studied. Lysosomes from homogenates of rat kidney cortex were isolated by differential centrifugation. These lysosomes were incubated at 37 degrees C with widely varied concentrations of sodium aurothiomalate and sodium aurothiosulphate for 5, 35, and 65 minutes. Acid phosphatase activities were measured and used as an i...
متن کاملExcited States of Gold(I) Compounds, Luminescence and Gold-Gold Bonding
It has long been established by Khan that the superoxide anion, O(2) (-), generates singlet oxygen, O(2) (1)Delta(g), during dismutation. Auranofin, gold-phosphine thiols, beta-Carotene, and metal-sulfur compounds can rapidly quench singlet O(2). The quenching of the O(2) (1)Delta(g), which exists at 7752 cm(-1) above the ground state triplet, may be due to the direct interaction of the singlet...
متن کاملAssessment of a cluster of gold nanoparticles effect on cell absorbed dose using the Geant4 toolkit
Introduction: Radiotherapy plays a vital role in cancer treatment. To establish a new potency in radiosensitize tumor cells, delivery of High-Z materials is offered. To date, several simulation geometries have been applied to define simulation sets. The clustering of nanoparticles (NPs) within the cells is a prominent parameter usually ignored in simulation studies. <stro...
متن کاملCompounds with a Discrete Supertetrahedral Cluster
The cluster compounds K10Zn4Sn4S17, K10Mn4Sn4S17, K10Fe4Sn4S17, K10Co4Sn4S17, Cs10Cd4Sn4S17 and K10Zn4Ge4S17 are described. The structures of these compounds, refined by single-crystal X-ray diffraction techniques, contain the discrete cluster [M4M 4S17] (M Zn, Mn, Co, Fe, Cd; M Sn or Ge) which has the structure of Si8C17H36. It is built from the sulfurconnected tetrahedral SnS4 and MS4 units w...
