Sažetak

Ammonium hydrogen maleate, NH4+C4Ha04- crystallizes in the
orthorhombic system with a = 0.4616(1), b = 0.8085(2), c = 1.6410(5)
nm, Z = 4 in space group Pbcm, and is isostructural with the analogous
potassium salt. The crystal structure has been refined from
diffracton1eter data to conventional R and Rw of 0.052 and 0.065
for 690 reflexions [I> 3 a (I)]. Minor changes in the crystal struc-·
ture were observed due to formation of N-H · · · 0 hydrogen bonds.
