Thiouracils and Their Tautomers with Water

Interaction of Thiouracils and Their Tautomers with Water 

383 A and the corresponding bond angles of 174.5° and 142.3°. All hydrogen bonds in both these complexes lie in the molecular plane. It is highly worth noticing an appearance of a rather short Si0-H- -Ow bond with the length of 

807 A that is by only 0.052 A longer than the adjacent hydrogen bond in the water dimer.
