Hammer & Screwdriver Many ways to do, but here is one

Code:
> cat in_file
@<TRIPOS>MOLECULE
core; [Isoc-015]
41 42 2
SMALL
NO_CHARGES
(...)
@<TRIPOS>MOLECULE
core; [Isoc-167]
41 41 2
SMALL
NO_CHARGES
(...)
@<TRIPOS>MOLECULE
core; [Isoc-085]
41 42 2
SMALL
NO_CHARGES
(...)
@<TRIPOS>MOLECULE
core; [Isoc-267]
41 41 2
SMALL
NO_CHARGES
(...)

Code:
> cat mk_file
#! /usr/bin/bash
#
# reads in_file
# creates sequentially numbered output files

count=0000
out_f="molecule"
while read zf
   do
   char1=$(echo "$zf" | cut -c1)
   if [ $char1 = "@" ]
      then
      count=$((count+1)) 
      countt=$(printf "%.4d" "$count")
      out_file="$out_f""$countt"
   fi
   echo $countt "$zf"
   echo "$zf" >>$out_file 
done<in_file

Program execution displays progress and builds files
Code:
> ls molecule*
molecule0001  molecule0002  molecule0003  molecule0004

Note that I designed to count from 0001 to 9999 for molecule filenames.
