Bromo ligand

These examples show that when information is not needed to identify the compound, it is omitted from the name. In the first name, for instance, it is not necessary to tell how many sodium ions are present, because we can deduce the number from the name of the complex anion. In the second name, the oxidation state of zinc is omitted because it is always +2. In the fourth name, the single bromo ligand is not preceded by the prefix mono. 

V) [37], frans- Fe(NCR)(depe)2 2+ (electron-poorer, 5 = 1-7-2.0 V) [35], with a N2, CNR, or NCR ligand. The strong electron-release from the trans bromo ligand in the first center, in contrast with the appreciable r-electron acceptance by the trans- 2, CNR, or NCR ligands in the other centers, hampers the electron-donation from the cyanamides, whereas the opposite effect occurs for the other metal sites. 

The Ni(II) complex of a 16-membered macrocycle, 2,7-dimethyl-3,6 -(1,1 - (2,2 - biimidazole) -1,3,6,8,11,14 - hexaazacyclohexadeca -1,7 -diene, 22, was synthesized by Schiff base condensation of the Ni(II)-triethylenetetramine complex and 1,1 -diacetyl-2,2 -bisimidazole (29). The Ni(II) complex formed square-planar geometry with iodide or perchlorate anions and an octahedral structure with chloro or bromo ligands. 

A recent X-ray crystal structure determination on mer-Os(NCMe)Br3(PPh3)2 shows the Os—N distance to be 2.024(10) A with the bromo ligand trans to it at 2.499(1) A the mean Os—P distance is 2.419 A and the trans bromo ligands are at 2.490 A. The complex was made by treating (Bu"4N)2-[Os2Br10] in acetonitrile with triphenylphosphine.382... 

The trinuclear molybdenum complex [Mo3(p,3-Se)(p.2-Se2)3 Se2P(OCH2 CH3)2 3]Br was synthesized by selective substitution of the bromo ligands in [PPh4]2[Mo3(p3-Se)(p2-Se2)3Br6] with bidentate ligands [Sc2P (OEt)2] . The crystal structure was determined by X-ray diffraction and the P and Se NMR spectra confirm that the cation persists in solution." ...
