Is there a chemical that has the bond structure like below?

enter image description here

There are 5 atoms linking together. Two of them have 4 bonds. (They are different atoms.) Another two of them have 3 bonds. (They can be either same or different atoms.) The last atom has only 2 bonds.

Are there such kinds of chemicals?

Unlikely., based on what you've described. I'll wait to see the picture. – Lighthart Feb 25 '13 at 5:46

To clarify - does the structure have to be composed solely of carbon atoms? With no hydrogens? Or is it a saturated alkane? – Richard Terrett Feb 25 '13 at 7:51
The OP indicates that they can be different atoms. A compound with formula $\ce{C2B2O}$ has the correct valences to accomplish that structure, but I am unsure if it exists. – Ben Norris Feb 25 '13 at 11:36
@BenNorris If it does, that is going to be one unhappy molecule, what with how far from tetrahedral that central carbon is. I suspect it would not exist for very long... – Canageek Feb 25 '13 at 15:27
