Abstract

The serendipitous discovery of the crystal structure of seven-member chelate of hydrated tris-(cis-vinyl-1,2 – bis (diphenylphosphineoxide))manganese(ii)perchlorate complex, Mn(cis-Ph2 P(O)CH=CHP(O)Ph2 )3 (ClO4 )2 .(H2 O) and the subsequent synthesis and characterization of related complexes

Abstract:

A hydrated tris-( cis-vinyl-1,2 –bis(diphenylphosphineoxide))manganese(II)perchlorate, [Mn(cisPh2 P(O)CH=CHP(O)Ph2 ) 3 ](ClO4 )2 .(H2 O) crystal structure has been determined and characterized. The complex was serendipitously discovered while attempting to obtain crystal of its bis-ligand analogue. In its structure the the monoclinic crystal is unique in coordination chemistry in that it contains a rare strained seven-member chelate ring system. Six or five coordinate complex are common but not seven-membered ring systems. The complex was then synthesized which shows to be a white air stable complex.
