However, the aluminum(III) ion actually reacts with six water molecules to form a stable complex ion, and so the more explicit representation of the dissolution process isAl(NO3)3(s)+6H2O(l)⇋Al(H2O)63+(aq)+3NO3-(aq)Al(NO3)3(s)+6H2O(l)⇋Al(H2O)63+(aq)+3NO3-(aq)...
Hydrohalide salt (II) has two formula units in the asymmetric unit that are related by a pseudo-inversion center. The dominant hydrogen-bonding interactions involve the chloride ion and result in R42(8) rings linked to form a ladder-chain structure. The chains are joined by N—HCl and N—...
The invention relates to novel imidazo[1,2-a]pyrimidines corresponding to the formula: <IMAGE> in which each of R2 and R3 denotes hydrogen, C1-C8 alkyl optionally substituted by a C3-C7 cycloalkyl, C2-C5 alkenyl, C3-C7 cycloalkyl or C7-C15 aralkyl, or R2 and R3 form an alkylene, ...

Bis (ethanediamine) complex cations of Cu II and Ni II react with formaldehyde and diethyl- (or dimethyl-) malonate to form complexes of 6,6,13,13-tetracarbomethoxy- (or carbethoxy-) 1,4,8,11-tetraazacyclotetradecane macrocycles. These... Ershov,Y A.,Nasledov,... - 《Chemistry of Hete...
Lithium ion provides a useful and specific form of chemotherapy for manic and hypomanic episodes, although its antimanic effect may be delayed for as long as a week or more, requiring the use of an antipsychotic agent in the initial period to control the behavior of very disturbed patients. ...
