Let (X,σ) be a symplectic space admitting a complex structure and let R(X,σ) be the corresponding resolvent algebra, i.e. the C*-algebra generated by the resolvents of selfadjoint operators satisfying canonical commutation relations associated with (X,σ). In previous work this algebra was shown to provide a convenient framework for the analysis of quantum systems. In the present article its mathematical properties are elaborated with emphasis on its ideal structure. It is shown that R(X,σ) is always nuclear and, if X is finite dimensional, also of type I (postliminal). In the latter case dim(X) labels the isomorphism classes of the corresponding resolvent algebras. For X of arbitrary dimension, principal ideals are identified which are the building blocks for all other ideals. The maximal and minimal ideals of the resolvent algebra are also determined.
