I don't think that this is possible by only crons means (at least not to my knowledge). What you could do is put something into the script which makes it run the "action"-part only every other run:
On the first run the script will not find /some/file, so it will create it and exit. On the second run it will remove it and then proceed to do whatever it is supposed to do. On the next run it won't find the file (because it removed it) and therefore will only create it and then exit, ....
This script can be used weekly in cron but will do its intended purpose only every other week.

run-parts
RUN-PARTS(8) System Manager's Manual RUN-PARTS(8)NAME
run-parts - run scripts or programs in a directory
SYNOPSIS
run-parts [--test] [--verbose] [--report] [--lsbsysinit] [--regex=RE] [--umask=umask] [--arg=argument] [--exit-on-error] [--help] [--ver-
sion] [--list] [--reverse] [--] DIRECTORY
run-parts -V
DESCRIPTION
run-parts runs all the executable files named within constraints described below, found in directory directory. Other files and directo-
ries are silently ignored.
If neither the --lsbsysinit option nor the --regex option is given then the names must consist entirely of ASCII upper- and lower-case let-
ters, ASCII digits, ASCII underscores, and ASCII minus-hyphens.
If the --lsbsysinit option is given, then the names must not end in .dpkg-old or .dpkg-dist or .dpkg-new or .dpkg-tmp, and must belong to
one or more of the following namespaces: the LANANA-assigned namespace (^[a-z0-9]+$); the LSB hierarchical and reserved namespaces
(^_?([a-z0-9_.]+-)+[a-z0-9]+$); and the Debian cron script namespace (^[a-zA-Z0-9_-]+$).
If the --regex option is given, the names must match the custom extended regular expression specified as that option's argument.
Files are run in the lexical sort order (according to the C/POSIX locale character collation rules) of their names unless the --reverse
option is given, in which case they are run in the opposite order.
OPTIONS --test print the names of the scripts which would be run, but don't actually run them.
--list print the names of the all matching files (not limited to executables), but don't actually run them. This option cannot be used with
--test.
-v, --verbose
print the name of each script to stderr before running.
--report
similar to --verbose, but only prints the name of scripts which produce output. The script's name is printed to whichever of stdout
or stderr the script first produces output on.
--reverse
reverse the scripts' execution order.
--exit-on-error
exit as soon as a script returns with a non-zero exit code.
--lsbsysinit
use LSB namespaces instead of classical behavior.
--new-session
run each script in a separate process session. If you use this option, killing run-parts will not kill the currently running
script, it will run until completion.
--regex=RE
validate filenames against custom extended regular expression RE. See the EXAMPLES section for an example.
-u, --umask=umask
sets the umask to umask before running the scripts. umask should be specified in octal. By default the umask is set to 022.
-a, --arg=argument
pass argument to the scripts. Use --arg once for each argument you want passed.
-- specifies that this is the end of the options. Any filename after -- will be not be interpreted as an option even if it starts with
a hyphen.
-h, --help
display usage information and exit.
-V, --version
display version and copyright and exit.
EXAMPLES
Print the names of all files in /etc that start with `p' and end with `d':
run-parts --list --regex '^p.*d$' /etc
