We report the results of the first search for Standard Model and baryon-number-violating two-body decays of the neutral

B

mesons to

Λ^{0}

and

Ω_{c}^{(*) 0}

using

711 {fb}^{- 1}

of data collected at the

ϒ (4 S)

resonance with the Belle detector at the KEKB asymmetric-energy

e^{+} e^{-}

collider. We observe no evidence of signal from any such decays and set 95% confidence-level upper limits on the products of

B^{0}

and

{\bar{B}}^{0}

branching fractions for these two-body decays with

B (Ω_{c}^{0} \to π^{+} Ω^{-})

in the range between

9.5 \times 10^{- 8}

and

31.2 \times 10^{- 8}
