N-(6-Amino-3, 4-dihydro-3-methyl-5-nitroso-4-oxopyrimidin-2-yl) methionine

Abstract:

The absolute configuration of the title compound, CIoH15NsO4S, has been determined and is in agree-ment with that of the starting material, L-methionine. Two identical hydrogen-bonded buckled sheets run par-allel to the [101] and [i01] planes. Molecules lying in either of these planes are linked together by a ring struc-ture to form these sheets, in which two chains of mol-ecules run antiparallel to each other along the b axis. A further hydrogen-bonded ring structure links the [10i] and [101] sheets together, resulting in an infinite three-dimensional hydrogen-bonded network. Comment Our interest in amino acid/nucleobase adducts is in their use as intermediates in the formation of metal complexes which have potential biological applica-tions. The coordinating ability of the title compound, HL, is demonstrated by the preparation of three solid metal-ligand species,(ZnL2" 2H20) n,(CdL2-3H20),, and (MnL2. 3H20),,. In …
