zero volume : can anyone check my poscar?

[tube77]

Hi.
I wonder if someone can check my POSCAR.
I keep receiving below message which I guess there's something wrong with my POSCAR.

| The distance between some ions is very small |
| please check the nearest neigbor list in the OUTCAR file |

Thank you.

Very weird input. You have to leave a space between number and minus sign (bottom part of coordinates). Are you sure they are fractional coordinates anyway?

Cheers,

Thank you Alex.
As you mentioned, the problem was from the coordinate system.
I simply switch Direct to Cartesian then it runs.
I appreciate again.
