AS i know Facebook chat is running on XMPP protocol. It is decentralised, but not P2P. It is similar to email - there is no central server, but lots of domain servers talking to each other and taking care of their clients. I am think about that is it possible to get user IP address who chat with us with coding or programming if so then how?

No, its not possible.
RFC 6120: Extensible Messaging and Presence Protocol (XMPP): Core states the following in Section 13.10: Information Leaks:
13.10.1. IP Addresses A client's IP address and method of access MUST NOT be made public by a server (e.g., as typically occurs in [IRC]).
If a client requests its own IP address, that policy is not violated. However, a server MUST NOT return the IP address of another client (e.g., if a connected client sends a SIC request to the bare JID of another user); instead, it MUST return a forbidden error.
