Subject: defstruct question

How can I define data structures that are pairs using defstruct?
How can I define data structures that contain pairs? What I want
to say is:

(defstruct (name (:type cons)) a b)

intending to create a thing of the form (name-a . name-b)

how can I name subfields?

(defstruct name (a :type cons :field-names '(kar kdr)))

intending to create a thing like

#((name-a-kar . name-a-kdr))
