Your create database statement is slightly wrong. If you look at the syntax it is

create database <dbname> ON (Name=<logical name for file>, filename='<filename>')

LOG ON (Name=<logical name for file>, filename='<filename>')

You have combined the logical name for file and filename and ommitted the name and filename keywords.
