Rhomboid

Bromoacetic acid [79-08-3] (BrCH2COOH), mol wt 138.96, C2H3Br02, occurs as hexagonal or rhomboidal hygroscopic crystals, mp 49°C, bp 208°C, 1.9335, 1-4804. It is soluble in water, methanol, and ethyl ether. Bromoacetic acid undergoes many of the same reactions as chloroacetic acid under... 

Iodine is a bluish black, crystalline soHd having a metallic luster. It is obtained in shiny flakes or prills that can be easily cmshed to powder. Iodine crystallines in rhomboidal plates belonging to the triclinic system.

The interesting compound Ba MogOig (17,22) contains tetranuclear rhomboidal cluster units, tied into infinite chains by Mo-O-Mo bonding as represented in the connectivity ] o ed in sites along tunnels... 

In one pair of chains the rhomboidal cluster units have five Mo-Mo bonds of nearly equal length (regular units), and in the other pair the (distorted) rhomboidal units have three short and two long Mo-Mo bonds. Figure 3 shows how these rhomboidal units are bound together within the infinite chains. A comparison of Mo-Mo and selected Mo-0 bond distances for the regular and distorted cluster units is given in Table III.

The structure of an adduct HReOs3(CO)15 has recently been determined by Churchill (257) this was isolated as a product of the reaction of Re(CO)3 with Os3(CO)12 by Mays and Knight (238). The structure is based on a rhomboid distribution of metal atoms (see Fig. 61). The hy-... 

The compound debromoisocymobarbatol from Florida Keys specimens inhibits parrotfishes, the fish Lagodon rhomboides, and the amphipod Hyale macrodactyla (Park et al. 1992). Cymopol from Florida inhibits the gastropod Littorina littorea (Targett and McConnnell 1982). Cymopol from Caribbean inhibits reef fishes (Hay et al. 1987)... 

L. rhomboides, S. schlegeli, and S. sordidus and the sea urchins Arbacia punctulata and D. savignyi acutilol A inhibit A. punctulata, L. rhomboids, and S. schlegeli and acutilol B inhibits S. schlegeli (Cronin et al. 1997)... 

Specimens from Radio Is., North Carolina (not a true tropical system, see text for details) Pachydictyol A inhibits the sea urchin A. punctulata and dictyol A acetate inhibits this sea urchin species, the amphipod Ampithoe longimana, and the pinlish /,. rhomboides (Bolser and Hay 1996). Pachydictyol A, dictyol B acetate, dictyol E, and dictyodial, also obtained from the same specimens, cause larval mortality, abnormal development, and reduced growth in bryozoans and hydroid species (Schmitt et al. 1998)... 

Low susceptibility to reef fishes in Florida and produces secondary metabolites (Paul and Hay 1986). Specimens from Radio Is., North Carolina Pachydictyol A inhibits the fish Diplodus holbrooki. This compound and dictyol B inhibit the sea urchin A. punctulata (Hay et al. 1987) both compounds from North Carolina also inhibit the fish A. rhomboides (Hay et al. 1988b)... 

We recently reported on the cluster Gaf, Rx2 (R = SiPh2Me) 67 in which the mean oxidation state of the gallium atoms is +1 [105] (Figure 2.3-18). After cleavage of two R groups the formation of an octahedral Ga<,R<, precloso unit analogue to the tetrahedral Ga4R4 cluster (cf. Section 2.3.3.1) could be assumed. Model calculations have shown however that a rhomboid Ga6 unit with two naked Ga atoms would be favored over the precloso cluster [105],...
