no, that won't even make it through the compiler. 

try

union {
    unsigned short s;
    char c[2];
} u;


u.s = 0x3132;

printf("c[0] = %c  c[1] = %c\n", u.c[0], u.c[1]);

I doubt that this is what you really want, so you could do

char c[2];
unsigned short s = 0x3132;

c[0] = s >> 8;
c[1] = s & 0xff;

which allows you to determine the order in which the bytes are put into
the char array instead of depending on how a short might be stored on a
given architecture. 

I am not sure this is what you really want to do either, but its what
you asked for.
