Nitrogen trichloride, structure

Note that sometimes an effort is ihade in drawing the structure of a molecule to indicate the spatial configuration the structure shown here for nitrogen trichloride is supposed to indicate that the molecule is pyramidal, with the chlorine atoms approximately at three corners of a tetrahedron alx)iit the nitrogen atoiii. 

Similarly there is no doubt about nitrogen trichloride, NCI3, an oily molecular substance composed of two non-metals. Its molecules have the cpvalent structure...

The product of interaction of sodium azide and phosphorus trichloride occasionally exploded on warming from 0°C to ambient temperature, but was examined safely in solution. The structure of the explosive product is determined as the title compound [1], rather than pentaazidophosphorane as originally reported [2], It contains some 82% of nitrogen. 

Complex Formation. B-Trichloroborazine was reported to readily form crystalline adducts of uncertain structure with pyridine (131). The Lewis acids aluminum tribromide or gallium trichloride form 1 1 adducts with hexamethylborazine (eq. 36) in which the metal atom coordinates with a nitrogen with loss of planarity of the ring (132,133). 

When hydrated rhodium trichloride is allowed to react with (78 Y = OMe, NMe Z = As), complexes of empirical formula [RhCl3(78)2] are obtained. The orange-red dimethylaminophos-phine complex has been shown to have the meridional structure (79), 957-959 However, one chloro ligand is labile and can be replaced in the inner coordination sphere by the previously uncoordinated nitrogen atom of the second neutral ligand. This process is enhanced by allowing the complex to react with metal salts whose anions are of low coordinating power (Scheme 37).957...
