If you will put element names in correct positions then refmac may have a chance to find it. Here is corrected positions:
ATOM 1893 O HOH A 258 -8.934 52.268 49.467 0.00 66.53 O ATOM 1894 ZN ZN B 1 -10.456 38.580 26.267 1.00 57.36 ZN+2 ATOM 1895 O HOH C 1 -5.932 42.917 25.589 1.00 24.02 O In your case all element names are moved towards left and B value of ZN is in incorrect position also.
