Isolation and structural determination of two derivatives of the elusive carbamic acidDedicated to Professor Heinrich Vahrenkamp on the occasion of his 60th birthday anniversary in recognition of his outstanding contributions to inorganic chemistry.
Abstract
The dibenzyl-substituted carbamic acid (PhCH2)2NC(O)OH (1), its deprotonation product [(PhCH2)2NH2]- [(PhCH2)2NCO2] (2) and CoCl(NO)2[PhP(OCH2CH2)2NC(O)OH ]·2MeCOMe(3·2MeCOMe) are reported, the diffractometric study showing the carbamic acids 1 and 3 to be paired through hydrogen bonds.
